What Is Skin Cancer Surgery?

Skin cancer surgery refers to a group of surgical procedures used to remove cancerous or precancerous skin growths. The goal is to eliminate cancer cells, minimize the risk of recurrence, and preserve healthy tissue and appearance. Surgery is often used for basal cell carcinoma, squamous cell carcinoma, melanoma, and other skin cancers when detected early or when lesions are high‑risk.

Why Surgery Is Performed

Surgery is recommended when skin cancer is confirmed or strongly suspected based on biopsy, imaging, or clinical findings. Your surgeon will choose the most appropriate technique based on the type, size, depth, and location of the cancer, as well as your overall health and cosmetic considerations. Early surgical removal offers the best chance for cure and limits the chance of spread.

Types of Skin Cancer Surgery

Excisional Surgery

Excisional surgery involves removing the tumor along with a margin of healthy tissue around it. This technique is commonly used for many types of skin cancer and provides tissue for pathology to confirm complete removal of cancer cells.

Mohs Micrographic Surgery

Mohs surgery is a highly specialized technique often used for basal cell carcinoma and squamous cell carcinoma, especially on the face, ears, or other sensitive areas. During Mohs surgery, the surgeon removes the cancer layer by layer and examines each layer under a microscope until clear margins are achieved. This maximizes cancer removal while sparing healthy tissue.

Curettage and Electrodessication

This method involves scraping away superficial cancers with a curette followed by controlled cautery (electrodessication) to destroy residual cancer cells. It’s frequently used for small, low‑risk basal and squamous cell cancers.

Sentinel Lymph Node Biopsy (for Melanoma)

For melanoma — a more aggressive skin cancer — a sentinel lymph node biopsy may be performed at the time of tumor removal to check for early spread to lymph nodes. This helps guide staging and treatment decisions.

What to Expect During Surgery

Most skin cancer surgeries are performed under local anesthesia in an outpatient setting. You will be awake but the area will be numb. For extensive lesions or when combined with other procedures, sedation or general anesthesia may be used. Your surgeon will explain the expected approach and whether reconstruction is needed at the time of excision.

Reconstruction After Skin Cancer Removal

Depending on the size and location of the defect after tumor removal, reconstructive techniques may be used to restore form and function. These can include direct closure, skin flaps, or skin grafts. The reconstructive plan is individualized to achieve the best cosmetic and functional outcome.

Recovery and Aftercare

After surgery, you’ll be given instructions for wound care, pain control, and activity restrictions. Most people experience mild discomfort, swelling, or redness around the surgical site that resolves over time. Keeping the area clean and following your surgeon’s guidance helps ensure optimal healing. Follow‑up visits are important to monitor healing and check for any signs of recurrence.

Benefits of Skin Cancer Surgery

  • Removal of cancerous tissue with clear margins
  • Reduced risk of cancer recurrence or progression
  • Preserved appearance and function, especially with Mohs or reconstructive techniques
  • Ability to tailor treatment based on pathology results

Risks and Considerations

As with any surgical procedure, skin cancer surgery carries some risks including bleeding, infection, scarring, changes in sensation, and, rarely, wound healing problems. Risk is influenced by the size and location of the lesion, your overall health, and whether reconstruction is needed. Your surgeon will explain risks specific to your case and how they plan to minimize them.

Frequently Asked Questions

Most basal cell carcinomas, squamous cell carcinomas, and melanomas are treated surgically when appropriate. Other rare skin cancers may also require surgical removal.
Most procedures are done under local anesthesia, so you should not feel pain during surgery. Mild discomfort afterward is common and controllable with prescribed or over‑the‑counter medication.
Mohs micrographic surgery removes cancer layer by layer with immediate microscopic evaluation to ensure complete removal while preserving as much healthy tissue as possible. It’s especially valuable for cancers in cosmetically sensitive or high‑recurrence areas.
Yes, any skin cancer removal will leave a scar. Surgeons use techniques to minimize scarring, and reconstructive options are available when needed.
Yes, regular follow‑up is important to monitor healing and check for recurrence or new skin cancers, especially for patients with a history of sun exposure or multiple lesions.
Recurrence is possible but uncommon when clear margins are confirmed. Follow‑up exams and skin surveillance help detect new or recurrent disease early.
