What is Mohs Surgery and How Does it Work?

Mohs surgery, also known as Mohs micrographic surgery, is a specialized surgical technique used to treat skin cancer. It is primarily used for basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), which are the two most common types of skin cancer. The procedure involves removing thin layers of cancerous tissue one at a time and examining them under a microscope until no more cancer cells are detected.

The process begins with the surgeon numbing the area with local anesthesia. Once the area is numb, the surgeon removes a thin layer of tissue containing the visible tumor. The tissue is then processed and examined under a microscope by the surgeon, who looks for any remaining cancer cells at the edges of the removed tissue. If cancer cells are found, another layer of tissue is removed from the specific area where the cancer cells were detected. This process is repeated until no more cancer cells are present.

Mohs surgery differs from other skin cancer treatments in its precision and ability to spare healthy tissue. Traditional excisional surgery involves removing the visible tumor along with a margin of healthy tissue around it. This can result in larger scars and a higher chance of recurrence. Mohs surgery, on the other hand, allows for the removal of only the cancerous tissue, minimizing damage to healthy tissue and reducing the risk of recurrence.

Who is a Candidate for Mohs Surgery?

Mohs surgery is typically recommended for patients with basal cell carcinoma (BCC) or squamous cell carcinoma (SCC) that meets certain criteria. These criteria include:

– Large tumors or tumors in high-risk areas such as the face, ears, nose, lips, or genitals.
– Tumors with ill-defined borders or aggressive growth patterns.
– Tumors that have recurred after previous treatment.
– Tumors in areas where preserving healthy tissue is important for functional or cosmetic reasons.

In addition to these criteria, factors such as the patient’s overall health, age, and personal preferences may also be taken into consideration when determining candidacy for Mohs surgery.

Mohs surgery offers several benefits for certain patients. For those with large tumors or tumors in high-risk areas, Mohs surgery allows for the removal of the cancer while preserving as much healthy tissue as possible. This can result in better cosmetic outcomes and reduced functional impairment compared to other treatment options. Additionally, Mohs surgery has high cure rates, making it an attractive option for patients who want the best chance of complete tumor removal.

What to Expect During the Mohs Surgery Procedure

During the Mohs surgery procedure, you can expect the following steps:

1. Anesthesia: The surgeon will administer local anesthesia to numb the area being treated. In some cases, sedation or general anesthesia may be used if the procedure is more extensive or if the patient prefers it.

2. Tumor removal: The surgeon will remove the visible tumor along with a small margin of surrounding healthy tissue. This tissue is then processed and examined under a microscope.

3. Mapping and examination: The surgeon will create a detailed map of the removed tissue and examine it under a microscope to check for any remaining cancer cells. This process may take some time, as each layer of tissue needs to be carefully examined.

4. Additional tissue removal: If cancer cells are found at the edges of the removed tissue, the surgeon will remove another layer of tissue from the specific area where the cancer cells were detected. This process is repeated until no more cancer cells are present.

5. Closure: Once all the cancer cells have been removed, the surgeon will discuss options for wound closure. This may involve sutures, skin grafts, or other techniques depending on the size and location of the wound.

The length of the procedure can vary depending on factors such as the size and location of the tumor, the number of layers that need to be examined, and the complexity of wound closure. On average, Mohs surgery can take several hours to complete.

How Long Does Mohs Surgery Take?

The length of a Mohs surgery procedure can vary depending on several factors. These factors include:

– Size and location of the tumor: Larger tumors or tumors in difficult-to-reach areas may require more time for removal and examination.
– Number of layers: The number of layers that need to be examined under a microscope can vary depending on how deep the cancer cells extend into the skin.
– Complexity of wound closure: Some wounds may require more complex closure techniques, such as skin grafts or flaps, which can add to the overall procedure time.

On average, a Mohs surgery procedure can take several hours to complete. However, it is important to note that each case is unique, and the length of the procedure can vary significantly from patient to patient.

What Happens After Mohs Surgery?

After Mohs surgery, you will receive specific wound care instructions from your surgeon. These instructions may include:

– Keeping the wound clean and dry: You will be advised to avoid getting the wound wet for a certain period of time and to keep it covered with a sterile dressing.
– Applying ointments or creams: Your surgeon may recommend applying an antibiotic ointment or other topical medications to promote healing and prevent infection.
– Avoiding strenuous activity: You may be advised to avoid activities that could strain the wound or increase the risk of complications.
– Following up with your surgeon: You will need to schedule follow-up appointments with your surgeon to monitor the healing process and address any concerns or complications that may arise.

It is common to experience some discomfort, swelling, and bruising after Mohs surgery. These symptoms can usually be managed with over-the-counter pain medications and by following your surgeon’s instructions for wound care. It is important to contact your surgeon if you experience severe pain, excessive bleeding, signs of infection (such as increased redness, swelling, or pus), or any other concerning symptoms.

How Effective is Mohs Surgery for Skin Cancer Treatment?

Mohs surgery is highly effective for the treatment of skin cancer. The procedure has cure rates that are consistently higher than other treatment options, particularly for tumors in high-risk areas or tumors with aggressive growth patterns.

The success rates of Mohs surgery vary depending on factors such as the type and stage of the skin cancer being treated. However, studies have shown that Mohs surgery has cure rates ranging from 95% to 99% for primary basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). For recurrent tumors or tumors in high-risk areas, the cure rates can be slightly lower but still significantly higher than other treatment options.

Compared to other treatment options such as traditional excisional surgery or radiation therapy, Mohs surgery offers several advantages. These include:

– Higher cure rates: Mohs surgery has consistently higher cure rates compared to other treatment options, particularly for high-risk tumors or tumors in difficult-to-treat areas.
– Preservation of healthy tissue: Mohs surgery allows for the removal of only the cancerous tissue, minimizing damage to healthy tissue and reducing the risk of recurrence.
– Precise tumor removal: The microscopic examination of each layer of tissue allows for precise identification and removal of cancer cells, reducing the chance of leaving any behind.
– Improved cosmetic outcomes: By preserving healthy tissue and minimizing scarring, Mohs surgery can result in better cosmetic outcomes compared to other treatment options.

Risks and Complications Associated with Mohs Surgery

Like any surgical procedure, Mohs surgery carries some risks and potential complications. These can include:

– Bleeding: Some bleeding is normal after surgery, but excessive bleeding may require additional treatment or intervention.
– Infection: There is a risk of infection at the surgical site, which can be minimized by following proper wound care instructions and keeping the area clean.
– Pain or discomfort: It is common to experience some pain or discomfort after surgery, but this can usually be managed with over-the-counter pain medications.
– Scarring: While Mohs surgery aims to minimize scarring, some degree of scarring is inevitable. The extent of scarring can vary depending on factors such as the size and location of the tumor and the complexity of wound closure.
– Nerve damage: In rare cases, Mohs surgery can cause damage to nearby nerves, resulting in numbness or other sensory changes in the area.

To minimize the risks associated with Mohs surgery, it is important to choose a skilled and experienced surgeon who specializes in this technique. Additionally, following your surgeon’s instructions for wound care and attending all follow-up appointments can help ensure proper healing and reduce the risk of complications.
