Planning for reconstructive surgery is one of the most important decisions you can make following a skin cancer diagnosis. Mohs surgery is designed to remove cancer while preserving as much healthy tissue as possible, but reconstruction helps restore the treated area once the cancer has been cleared. For many patients, the right reconstruction plan can support healing, preserve function, minimize visible scarring, and restore confidence.

Dr. Vincent Hung offers Mohs surgery and reconstructive plastic surgery in Pasadena and Newport Beach, with a practice focused on skin cancer surgery, Mohs surgery, and reconstruction. During your consultation, Dr. Hung will help you better understand your diagnosis, treatment options, and reconstructive plan so you can move forward with greater comfort and clarity.

Why Mohs Reconstruction Requires Careful Planning

Mohs surgery removes skin cancer layer by layer while the tissue is examined until only cancer-free tissue remains. This surgical procedure is designed to preserve your natural tissue, removing only the affected areas while keeping the healthy skin intact. It’s best for patients diagnosed with common skin cancers, such as basal cell carcinoma and squamous cell carcinoma.

That precision matters because many skin cancers occur in visible or delicate areas. The nose, eyelids, ears, lips, and cheeks have limited extra tissue and complex shapes. A small cancer can sometimes leave a larger wound than expected once all microscopic cancer cells have been removed.

Different reconstruction techniques include:

• Direct closure: This involves safely bringing the wound edges together. It works best for smaller wounds or areas with enough surrounding skin.
• Local flap reconstruction: This uses nearby tissue to close the wound, helping to match color, thickness, and texture. It’s especially useful on the face, where contour matters.
• Skin or cartilage grafting: A skin graft uses tissue from another area, such as the head or other bodily areas. It’s then shaped and attached to the damaged area. This can be efficient in areas such as the nose or ear.
• Secondary healing: In some cases, a small wound may heal on its own. This option should be chosen only when your surgeon believes it will support a safe outcome.

The goal is not just to close the wound, but to support healing, preserve function, and help the repaired area blend as naturally as possible with your features.

What to Look for in a Plastic Surgeon for Mohs Reconstruction

When comparing providers, focus on qualifications directly related to skin cancer removal, facial anatomy, wound healing, and reconstruction. A plastic surgeon who understands Mohs surgery can plan repair around both cancer clearance and final appearance.

Important factors include:

• Training in Mohs surgery and skin cancer treatment
• Experience with reconstructive plastic surgery
• Knowledge of facial anatomy and function
• Experience repairing the nose, lips, eyelids, ears, and scalp
• A clear plan for post-operative care and follow-up
• Before-and-after photos that show a range of Mohs reconstruction cases
• A consultation process that explains your options without rushing you

For patients, that means the “best” choice is not always based on a title alone. You should look for a provider whose training and experience match the exact problem you need treated.

Questions to Ask Before Choosing Your Surgeon

Before choosing a plastic surgeon for Mohs reconstruction, ask direct questions. A qualified provider should welcome them.

Consider asking:

• How often do you perform Mohs reconstruction?
• Do you perform both Mohs surgery and reconstruction?
• What reconstruction options may fit my case?
• Will my repair be done the same day as Mohs surgery?
• What can I expect my scar to look like over time?
• How do you protect function in areas like the nose, lips, ears, and eyelids?
• What follow-up care will I need?
• Can I see before-and-after photos of similar cases?

Dr. Hung offers patients access to an extensive photo gallery of Mohs surgery and reconstruction photos. They show a wide spectrum of cases, from relatively straightforward to complex.

What to Expect During Your Consultation

Your consultation should give you a clear understanding of what may happen after your skin cancer is removed. In some cases, your surgeon can predict likely reconstruction options before Mohs surgery. In other cases, the final plan depends on the wound’s size and shape after all cancer cells have been cleared.

During your visit, you should expect to discuss:

• Where the skin cancer is located
• How Mohs surgery removes the cancer
• Possible reconstruction options
• Whether repair may happen the same day
• What kind of scar you may have
• How long swelling and bruising may last
• Activity restrictions after surgery
• Follow-up appointments and wound care

Dr. Hung’s practice philosophy emphasizes both optimal physical results and the pre-operative and post-operative counseling and care needed to support the best overall experience. Since it’s normal to feel anxious when skin cancer affects the face, a strong consultation should answer your questions, explain what is known, and clarify what cannot be determined until the cancer is fully removed.

Why Dr. Hung’s Background Matters for Mohs Reconstruction

Choosing the right Mohs reconstructive surgeon means placing your care in the hands of someone who understands the nuances of both skin cancer removal and reconstructive plastic surgery. For patients seeking Mohs surgery in Pasadena and Newport Beach, Dr. Vincent Hung provides comprehensive care that includes both cancer removal and reconstruction, helping patients move forward with a clear treatment plan and greater peace of mind.

Dr. Hung is triple board certified in Internal Medicine, Dermatology, and Plastic Surgery, placing him among a rare group of physicians with this level of specialized training. He also completed fellowship training in “Mohs micrographic surgery,” a specialized technique of skin cancer removal. Beyond his extensive experience with advanced Mohs surgical techniques, Dr. Hung takes a personalized approach to care, designing each treatment plan around your diagnosis, anatomy, healing needs, and aesthetic goals.

Mohs reconstruction requires expertise across several medical disciplines. Dr. Hung deeply understands the cancer removal process, how the skin heals after surgery, and which reconstructive options can best restore form, function, and appearance.

Why Facial Mohs Reconstruction Is Different

Mohs reconstruction on the face requires special attention because facial structures affect expression, breathing, blinking, speaking, eating, and overall appearance. A repair near the eyelid must protect eye closure. Lip reconstruction must consider movement and symmetry. A nasal reconstruction must account for contour, airway support, and skin thickness.

Dr. Hung specializes in reconstructive surgery around the nose, eyes, lips, scalp, and other intricate, extreme target areas. He understands that the tiniest millimeter can change both appearance and function. For patients with skin cancer around the face, he offers advanced Mohs surgical techniques that focus on leaving the smallest, least visible wound necessary for reconstruction.

FAQ About Choosing a Plastic Surgeon for Mohs Reconstruction

Do I need a plastic surgeon after Mohs surgery?

Not every Mohs wound requires a plastic surgeon, but reconstruction becomes especially important when skin cancer affects the face, nose, lips, ears, eyelids, or other delicate areas.

Can the same doctor perform Mohs surgery and reconstruction?

Yes, in some practices. Dr. Hung performs both Mohs surgery and subsequent reconstructive plastic surgery, and he applies his plastic and cosmetic surgery skills to achieve optimal post-Mohs reconstruction outcomes.

What makes Dr. Hung qualified for Mohs reconstruction?

Dr. Hung is triple board certified in Internal Medicine, Dermatology, and Plastic Surgery, and fellowship-trained in Mohs skin cancer surgery. He specializes in skin cancer surgery and reconstruction.

Will Mohs reconstruction leave a scar?

Any surgery can leave a scar. Scarring depends on the amount of reconstruction needed and the treatment site, but scars can be covered with makeup and are likely to fade over time.

How soon should I schedule a Mohs surgery consultation?

You should schedule a consultation as soon as you know Mohs surgery may be needed, especially if the skin cancer is on the face or another sensitive area. Early planning helps Dr. Hung discuss likely repair options and prepare you for post-operative recovery.

Why Your Mohs Surgery Consultation Matters

Mohs surgery removes skin cancer in stages while the tissue is examined during the procedure. Its progressive structure means only the affected tissue is removed continuously until your skin is cancer-free, preserving as much healthy tissue as possible.

This precision matters when your skin cancer appears in an area where preserving healthy tissue can affect your final result. Mohs surgery can conserve healthy tissue, provide complete cancer removal, and allow the smallest wound necessary for reconstruction.

Your consultation should connect those medical goals to your personal case. During your visit, Dr. Hung will explain your skin cancer type, location, risk factors, treatment options, and expected repair plan. He takes the time to evaluate your case and design a treatment plan tailored to your individual needs.

Questions to Ask About Your Diagnosis

Your diagnosis should guide the treatment plan. Skin cancer treatment often begins with a biopsy, which involves removing a small portion of the lesion and sending it to a lab for analysis.

Helpful questions about your diagnosis to ask during your consultation include:

• What type of skin cancer do I have?
• Is my skin cancer basal cell carcinoma, squamous cell carcinoma, melanoma, or another type?
• Is this cancer considered low or high risk?
• Are the borders clearly defined?
• Has the cancer shown aggressive features?
• Is this a new skin cancer or a recurrence?

These questions help you understand whether Mohs surgery is recommended for you. Mohs surgery is best for patients with common skin cancers that have a high recurrence rate.

Questions to Ask About Mohs Surgery in Pasadena

Your consultation should explain what will happen on the day of surgery. Using local anesthesia, Mohs surgery is performed on an outpatient basis. During the procedure, the visible cancer and a thin rim of tissue surrounding it are removed, mapped, analyzed, and removed again if remaining cancer cells are identified.

Ask Dr. Hung:

• Why do you recommend Mohs surgery for my case?
• How does Mohs surgery differ from standard excision?
• Will I be awake during the procedure?
• How long should I plan to be at the office?
• How many stages do you think may be needed?
• Will I know the same day if the cancer has been removed?

The Mohs procedure can be performed while the patient is awake, allowing it to be done in a medical office or surgical suite.

Questions to Ask About Reconstruction

With Dr. Hung, removal is not the only aspect of surgery. He offers an expert eye for reconstruction, especially important when skin cancer affects facial areas such as the nose, eyelids, lips, or other visible areas.

Your available reconstructive options will be discussed during consultation. These options can include direct closure, local skin flaps, skin grafts, or allowing very small superficial wounds to heal on their own.

Ask questions such as:

• Will I likely need reconstruction after Mohs surgery?
• What repair options may apply to my case?
• Will the reconstruction happen the same day?
• How will the repair protect function?
• What can I realistically expect my scar to look like?
• How long will healing and scar fading take?

Scars will fade over time, but the degree of scarring depends on the amount of reconstruction needed and the treatment site.

Questions to Ask About Recovery

A Mohs surgery consultation should help you plan your recovery before surgery day. While recovery varies case by case, patients should generally expect swelling and bruising around the treatment areas. You will also need to avoid strenuous activity and attend follow-up appointments over the next several weeks following treatment.

During your consultation, you should ask:

• How should I care for the wound after surgery?
• Will I need stitches removed?
• When can I return to work?
• When can I exercise again?
• What symptoms should prompt a call to the office?
• How many follow-up visits should I expect?

These questions help you prepare for the practical side of treatment and avoid surprises during the first few days after surgery.

Questions to Ask About Medications and Day-Of Planning

Medication review is an important part of surgical planning. You should inform Dr. Hung about any active medications and supplements that you may be taking, especially substances that thin your blood.

Ask Dr. Hung:

• Should I continue my prescription medications?
• Do I need to avoid aspirin, anti-inflammatory medications, or supplements?
• Should I eat before my appointment?
• Should someone drive me home?
• What should I bring on surgery day?
• Should I plan to be at the office for several hours?

Following surgery, patients should avoid aspirin or nonsteroidal anti-inflammatory drugs for at least three days. Your personal medication instructions may differ, so follow the directions given to you by Dr. Hung.

FAQ About Your Mohs Surgery Consultation

What should I bring to my Mohs surgery consultation?

Bring your biopsy results if available, a list of current medications and supplements, your medical history, insurance information, and any questions you want answered.

Will I find out if I need reconstruction during the consultation?

In many cases, Dr. Hung can discuss likely reconstruction options during the consultation. Your available reconstructive options are discussed during your consultation.

Should I ask about scarring before Mohs surgery?

Yes. Scarring fades over time but largely depends on the treatment site, the amount of reconstruction needed, and how you heal.

Can I ask whether standard excision is an option?

Yes. Your consultation with Dr. Hung should help you understand why Mohs surgery, standard excision, or another treatment may be recommended. More aggressive skin cancers may require additional treatment.

How long does Mohs surgery take?

Most Mohs surgeries can be performed in a single visit, as tissue analysis is part of the procedure. However, the total time may vary depending on the required amount of tissue to be removed.

Schedule a Skin Cancer Treatment Consultation in Pasadena, CA

Your Mohs surgery consultation should provide you with more than just a treatment date. It should give you a clear roadmap for cancer removal, reconstruction, recovery, and follow-up care.

If you have been diagnosed with skin cancer and are undergoing Mohs surgery, knowing how to prepare can help you feel calmer, more organized, and more confident before your procedure. Mohs surgery is often recommended when precision matters, especially for skin cancers on the face, nose, lips, ears, or other areas where preserving healthy tissue can affect both appearance and function. As a result, following your pre- and post-operative instructions is vital. This blog will discuss how to prepare for Mohs surgery and the best methods for facilitating a smoother recovery and long-lasting results.

Why Preparation Matters Before Your Mohs Procedure

Mohs surgery is usually performed as an outpatient procedure using local anesthesia, which means you are awake while the treatment area is numbed. Your surgeon removes the visible portion of the cancer, the tissue is examined under microscopic examination, and the process is repeated only where cancer cells remain until the tissue is cancer-free. It’s best for patients diagnosed with squamous cell carcinoma, basal cell carcinoma, or other aggressive cancer variants with a high risk of recurrence.

Because Mohs surgery happens in stages, appointment length can vary. While most Mohs surgical procedures take only a few hours, it’s best to plan for the day since your exact treatment time cannot always be reliably predicted.

Preparing ahead can help you avoid stress on the day of surgery. It also helps Dr. Hung review medications, plan your repair, and support a smoother post-operative recovery.

How to Prepare for Mohs Surgery With Medications

Before Mohs surgery, make sure your surgical team knows all the medications and supplements you take. This includes prescription, over-the-counter, and herbal supplements, as well as anything that may affect bleeding.

This step is especially important if you take:

• Blood thinners
• Aspirin or aspirin-containing products
• Anti-inflammatory medications
• Vitamin E, fish oil, or herbal supplements
• Heart, blood pressure, or diabetes medications
• Pain medications
• Any medication prescribed by another doctor

Do not stop a prescribed blood thinner or heart-related medication on your own. Dr. Hung may coordinate with your prescribing physician if a medication adjustment is needed. The safest plan is the one tailored to your medical history.

Patients should also avoid aspirin or nonsteroidal anti-inflammatory medication for at least three days after Mohs surgery. However, your personal instructions may vary, so follow the directions given by Dr. Hung and his care team.

Transportation Planning for Mohs Surgery

Mohs surgery is often performed with local anesthesia, allowing most patients to go home the same day. However, transportation still deserves careful planning prior to surgery.

You may want to arrange for someone to drive you home if:

• Your skin cancer is near the eye
• You feel anxious about surgery
• You expect a larger repair
• Your surgeon recommends that you avoid driving afterward

A ride can also make the day easier if your appointment takes longer than expected or if your bandage limits visibility, movement, or comfort.

If you are coming from Pasadena, Newport Beach, or another surrounding Los Angeles community, plan for traffic, parking, and extra time at the office. Since Mohs surgery may include waiting periods while cancerous tissue is processed and examined, it is better to keep the rest of your day clear.

What to Bring on the Day of Mohs Surgery

On the day of your surgery, consider bringing:

• A current medication and supplement list
• Your insurance card and identification
• A phone charger
• Reading material or headphones
• A snack or water, if allowed
• Any forms requested by the office
• A trusted driver or support person, if needed

You should also wear comfortable clothing. However, if your treatment area is on the face, head, or neck, make sure to wear a loose shirt that does not need to be pulled tightly over the treatment area.

Food, Clothing, and Personal Care Before Your Appointment

Unless instructed otherwise, you do not need to fast before Mohs surgery, as the procedure is commonly performed under local anesthesia. Eating a normal breakfast can help you feel more comfortable during the appointment, especially if the procedure takes longer due to a more extensive treatment.

On the day of surgery, avoid applying makeup, lotion, or skincare products near the treatment area unless approved. Keep the area easy to access, and avoid wearing jewelry that may interfere with positioning, bandaging, or complex reconstruction.

Day-Of Planning: What Happens During Mohs Surgery

On your day of surgery, the treatment area will be cleaned, marked, and numbed with local anesthesia. Dr. Hung will then remove the visible tumor along with a thin layer of surrounding tissue. All the margins are then mapped, prepared, and examined for any remaining cancer cells.

If cancer cells remain, another layer is removed only from the area where cancer persists. This process continues until the tissue shows no remaining cancer cells. This allows for complete removal without removing excessive amounts of healthy skin.

After the entire tumor and cancer has been removed, the area may be closed with stitches, repaired with a reconstructive technique, or, in select cases, allowed to heal on its own. Dr. Hung offers comprehensive reconstructive surgery options that allow for small, minimally visible wounds, including direct closure, local flaps, skin grafts, or natural healing.

Post-Operative Planning Before You Go Home

Before your surgery date, prepare your home for the first few days of the healing process. Set aside clean dressings, approved surgical wound care supplies, and any medications recommended by your surgeon. You may also want to prepare meals and adjust your work schedule accordingly.

Patients should expect swelling and bruising, depending on the treatment area. Strenuous exercise and physical activity should be avoided for up to three weeks or until cleared by Dr. Hung. Follow-up visits are scheduled over several weeks to monitor wound healing.

Proper post-operative care can promote optimal comfort, scarring, and natural-looking results. Contact your doctor’s office if you notice increasing pain, spreading redness, unusual drainage, fever, or any sign of poor wound healing that concerns you.

FAQ About Preparing for Mohs Surgery

Do I need to stop blood thinners before Mohs surgery?

Do not stop blood thinners or prescribed medications unless part of Dr. Hung’s instructions. Patients should still inform Dr. Hung about medications and supplements, especially blood thinners.

Should someone drive me home after Mohs surgery?

You may be able to go home the same day after Mohs surgery, but arranging a ride can be helpful. This is especially true if the surgery is near your eye, if your bandage may affect comfort or visibility, or if Dr. Hung recommends transportation support.

Can I eat before Mohs surgery?

How long should I plan to be at the office?

Plan to keep your schedule open for the day. Most Mohs procedures take less than four hours, but the length can be hard to predict, and some patients may be advised to plan for a full day.

What should I wear to Mohs surgery?

What to Know Before the Day of Your Mohs Procedure

Mohs surgery involves removing the visible tumor and the thin rim of tissue surrounding it. This tissue is then marked, mapped, and evaluated before any additional tissue is removed. If any additional cancer cells are discovered beyond the removed tissue, additional tissue is continuously removed until the surrounding area is completely free of remaining cancer cells.

Because Mohs surgery is performed in stages, the total appointment time can vary. While most procedures take around four hours, it’s recommended that you plan as if surgery could take all day.

You should arrive with your schedule clear, your medication list available, and your post-operative plans already arranged. If your surgery is near the eye, if you feel anxious, or if you expect a larger repair, having someone drive you home may make the day easier.

Step 1: Check-In and Surgical Preparation

When you arrive for Mohs surgery, the team will confirm your information, review the treatment site, and prepare you for the procedure. The surgical site is cleaned and marked before local anesthesia is used to numb the skin.

This first step helps make sure the correct area is treated and that you are comfortable before tissue removal begins. Once the area is numb, you may feel pressure, but you should not feel sharp pain during the removal.

Mohs surgery requires careful planning because Dr. Hung removes tissue precisely and tracks the origin of each section.

Step 2: The First Layer of Tissue Is Removed

After the area is numb, your surgeon removes the visible skin cancer along with a thin layer of surrounding tissue. This layer is intentionally conservative, as Mohs surgery is designed to remove cancer while preserving as much healthy skin as possible.

This is one of the biggest differences between Mohs surgery and standard excision. Instead of removing a wider margin and waiting for outside pathology results, Mohs allows the surgeon to evaluate the tissue during the appointment and continue treatment only where cancer cells remain.

Step 3: You Wait While the Tissue Is Processed

After each layer is removed, the tissue is examined under a microscope while the patient waits. A temporary bandage is placed over the area while the tissue is processed and examined. This analysis is often the longest part of the procedure, typically taking an hour between stages.

It may help to bring a book, headphones, a phone charger, or another quiet activity to help pass the time. Patients can also use the restroom or have a snack while waiting, but they should not leave until the procedure is complete.

The waiting period can feel stressful, but it is also what makes Mohs surgery so precise. The tissue map helps identify the exact area that needs additional treatment, if any remains.

Step 4: The Tissue Is Examined Under a Microscope

During the lab review, Dr. Hung and his team examine the edges and underside of the removed tissue. If no cancerous cells remain, the cancer removal portion of the procedure is complete. If cancer cells are still present, they can identify the exact area that needs to be removed.

This step is especially important for skin cancers on visible or delicate areas, such as the face, nose, lips, ears, eyelids, or scalp. Mohs surgery can be especially beneficial when tissue conservation, cosmetic outcomes, and functional concerns are important.

Step 5: Additional Layers Are Removed Only if Needed

If cancer cells remain after the first layer, another thin layer is removed only from the area where cancer persists. The tissue is processed again, and you wait while it is examined.

This process is repeated until the tumor and remaining cancerous tissue are completely removed, allowing the doctor to remove cancer cells while sparing as much healthy tissue as possible.

Some patients need only one stage. Others need more than one stage before the margins are clear. The number of stages you will need depends on your diagnosis, location, and surgical findings.

Step 6: Reconstruction or Wound Repair Is Planned

Once the cancer has been fully removed, the next step is repair. Depending on the size, depth, and location of the wound, Dr. Hung’s reconstruction techniques may involve direct closure, a local flap, a skin graft, or allowing a very small superficial wound to heal on its own. The most appropriate option will be discussed during your initial consultation.

For skin cancers on the head, face, nose, lips, ears, or other visible areas, reconstruction is not just about closing the wound. It is also about protecting function, supporting healing, and helping the repaired area blend as naturally as possible.

Step 7: Receiving Post-Operative Instructions

Before you leave, you will receive instructions for wound care, activity limits, medications, follow-up visits, and symptoms to watch for. Swelling and bruising may occur and persist for a few weeks. It’s important that you avoid strenuous activity or pressure on the treated area to promote proper healing. Follow-up appointments will be scheduled over the following weeks for routine check-ups.

Your instructions will likely include how to keep the dressing clean, when to change bandages, how to manage discomfort, and when to call the office. Our contact page also includes Mohs patient forms, wound-healing information, medication list forms, and wound care instructions for patients if needed.

Following your post-operative instructions can help support healing and reduce avoidable complications. If you notice increasing pain, spreading redness, unusual drainage, fever, or bleeding that does not improve with pressure, contact our office promptly.

What’s the Difference Between Mohs Surgery and Standard Excision?

Standard excision is a procedure that removes the visible skin cancer along with a margin of surrounding skin. The tissue is then sent to a lab, where the margins are checked for cancer cells. This is the most common treatment for basal cell carcinoma.

Mohs surgery works differently. During Mohs surgery, Dr. Hung removes the visible cancer and a thin layer of surrounding tissue, examines that tissue under a microscope, and repeats the process only where cancer cells remain. This procedure allows Dr. Hung to see where the cancer stops during treatment, which helps preserve as much healthy skin as possible.

When Standard Excision May Be Appropriate

Standard excision may be appropriate for early, low-risk skin cancers in areas where a small tissue margin can be removed safely. It’s an effective treatment for curing many early basal cell carcinomas or melanomas.

Standard excision may be considered when the cancer is:

• Small and low risk
• Clearly defined
• Located in an area with more available tissue
• Less likely to affect appearance or function
• Not recurrent or aggressive

If cancer cells are found in the margins after excision, additional treatment may be needed, which may include another excision, Mohs surgery, medication, or radiation therapy.

When Mohs Surgery May Be the Better Choice

Mohs surgery is often recommended for skin cancers that have a higher risk of returning, are large or aggressive, have unclear borders, or appear in areas where tissue preservation is important. It’s a tissue-conserving method that progressively removes affected tissue until only cancer-free skin remains, preserving healthy tissue while allowing complete cancer removal.

Mohs may be especially worth discussing if your skin cancer is:

• On the face, nose, lips, ears, eyelids, or scalp
• Recurrent after previous treatment
• Aggressive or fast-growing
• Large or difficult to clearly define
• In an area where scarring or tissue loss may affect function
• A basal cell carcinoma or squamous cell carcinoma in a higher-risk location

What to Expect During Standard Excision

During standard (traditional) excision, the surgical site is numbed with local anesthesia. Then, your surgeon removes any visible skin cancer along with a small amount of surrounding skin, called a margin, to address any cancer cells that may extend beyond what can be seen on the surface.

After removal, your tissue is sent to a lab for microscopic review to determine whether cancer cells remain at the edges. If the margins are clear, treatment may be complete. If some cancer cells remain, additional treatment may be recommended.

What to Expect During Mohs Surgery

Mohs surgery is also performed with local anesthesia. Using a scalpel, Dr. Hung removes your visible tumor as well as a thin rim of tissue around the affected site. The tissue is then dyed for orientation, mapped, processed, and examined. Any remaining cancerous tissue that is found will be repeatedly removed from the area until the tumor is completely gone.

After the cancer has been treated, the tissues will be replaced to prevent large, unappealing holes around your face or body. Dr. Hung performs varying degrees of reconstructive surgery depending on the wound size, location, and depth. Skin or cartilage grafts may be harvested from areas of your body with excess tissue and carefully reattached, sculpted, and blended with your natural features. Stitches are sewn to close the wound.

Recovery After Standard Excision

Following standard excision, you can expect mild swelling, bruising, tenderness, or tightness around the treatment area during the first several days. Most patients feel comfortable returning home shortly after the procedure, but proper post-operative care is crucial for healing, comfort, and scar management.

If stitches were used, they are typically removed during a follow-up visit, often within two weeks after surgery, depending on location and the surgeon’s instructions. Other post-operative instructions may include:

• Keeping the area clean
• Maintaining your surgical dressings
• Avoiding pressure and stretching that stresses the incision site
• Avoid strenuous exercise for a few weeks

Most wounds and side effects heal within a few weeks. Larger excisions may take longer based on the extent. During your follow-up visit, your surgeon will check the incision, review your healing progress, and communicate whether the pathology results indicate that additional treatment is needed.

Recovery After Mohs Surgery

After Mohs surgery, you may notice some swelling and bruising in the treatment area. However, these side effects should subside within a few weeks after surgery.

During this time, you may be instructed to avoid aspirin or other anti-inflammatory medications for at least three days and strenuous activity for up to three weeks or until cleared by Dr. Hung. If you’re experiencing pain or discomfort, Dr. Hung may recommend TYLENOL® for relief.

It’s also important to avoid lying or sleeping on the side with the treated area. Your follow-up visits will be scheduled over several weeks to monitor wound healing. You should expect some scarring depending on the extent of reconstruction needed and the treatment site, but it can be covered with makeup and fade over time.

FAQ About Mohs Surgery vs Standard Excision

Is Mohs surgery better than standard excision?

This depends on your skin cancer diagnosis, cancer location, and pathology. Standard excision is more appropriate for certain early, low-risk skin cancers. Meanwhile, Mohs surgery may be the better choice for skin cancers that are recurrent, aggressive, large, difficult to define, or located in areas where preserving healthy tissue is vital.

Does Mohs surgery leave a smaller scar?

For both procedures, your final scar will ultimately depend on the cancer size, depth, location, and reconstruction required. However, Mohs surgery generally provides many patients with ideal aesthetic results, as it removes only affected tissue while preserving as much healthy tissue as possible.

Are there any risks associated with standard excision?

While not common, certain risks associated with standard excision include pain, scarring, numbness, nerve damage, infection, and lymphedema, a swelling in the arms or legs.

Are there any risks associated with Mohs surgery?

Risks for Mohs surgery may include bleeding, tenderness, infection, itching, numbness, large holes around the treated area, or partial removal of the lips if the cancer is located there.

Will I know if all the cancer was removed the same day?

In most Mohs surgery cases, you will know whether the cancer was fully removed the same day. The removed tissue is examined during the procedure, and the process continues until no cancer cells remain. With standard excision, the tissue is sent to a lab after removal, so margin results may take longer.
