Skin Cancer Excisions

Basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and melanoma can all be treated with simple surgical excision. However, in certain situations—such as when the cancer is in a cosmetically or functionally sensitive area, has unclear borders, or requires the highest level of tissue preservation—Mohs micrographic surgery may be recommended for its added precision.

Any spot that is changing, bleeding, itching, or not healing should be checked by a dermatologist. Growths that enlarge quickly, form a crust, appear pearly or translucent, or have irregular or evolving borders often warrant a biopsy to determine whether removal is necessary.

A biopsy removes a small sample of a spot to determine what it is. An excision removes the entire skin cancer along with a margin of normal skin to ensure it’s fully treated. In most cases, a biopsy is performed first for diagnosis, and if cancer is confirmed, the area is later excised.

During the excision, you should not feel significant pain because of the local anesthetic, though you may feel pressure or slight pulling. After the procedur,e you may feel soreness, swelling or mild discomfort. Over-the-counter pain relief is often sufficient.

Recovery depends on the size and location of the excision and whether a flap/graft was required. Many wounds heal within 1–3 weeks; more complex repairs may take longer. You’ll receive specific post-care instructions (wound care, activity restrictions, sun protection).

Yes — while excision is very effective, no procedure guarantees a 100% cure rate. Recurrence depends on cancer type, size, location, and completeness of removal.

Most excisions take 15-20 minutes, depending on the size and location. More complex closures or reconstruction may take longer.

You can help minimize scarring by following your wound care instructions carefully, keeping the area moisturized, protecting it from the sun, and avoiding smoking. Gentle scar massage and the use of silicone scar sheets can also improve the final appearance.

Yes. Patients with a history of skin cancer should have routine full-body skin exams, usually every 6 months. Early detection significantly improves outcomes.

Light incidental exposure is usually fine, but direct sunlight can cause pigmentation changes and widen your scar. Providers often recommend avoiding peak sun hours and using physical barriers like hats and long-sleeve clothing until fully healed.

Yes. Skin tightness or pulling sensations are common, especially for larger excisions or those over high-tension areas like the back. This usually softens as the tissue remodels over several months.

Scars evolve for 12–18 months. They often appear pink or raised early on, then gradually flatten and fade. Sun protection, silicone gel, and sometimes laser treatments can help refine the final result.

Most patients can do light activity starting 3 days after the procedure, but vigorous exercise, heavy lifting, or stretching the treated area may cause the wound to reopen. Restrictions depend on the size and location of the excision.

Skin cancers continue growing over time. Delaying treatment can increase the size of the excision required, lead to deeper invasion, and complicate reconstruction or cosmetic outcomes.

The amount of skin removed is based on the type of skin cancer, its size, depth, and location. Your dermatologist follows evidence-based margin guidelines to ensure all cancerous cells are removed while preserving as much healthy tissue as possible.

Most excisions do require stitches to help the skin heal properly and minimize scarring. Depending on the depth of the excision, stitches may be placed just under the skin, on the surface, or both, and are usually removed within 1–2 weeks (unless dissolving stitches are used).

Yes. Having one skin cancer increases your risk of developing another. Routine full-body skin exams help catch new or changing lesions early when they are easiest to treat.

While excision is highly effective, no treatment offers a 100% guarantee. Regular follow-up visits and skin checks are important to monitor the treated area and detect any recurrence early.

Most excisions are performed under local anesthesia, which numbs the area completely while you remain awake. This provides excellent comfort and allows for a quick recovery without sedation side effects.

Follow your post-care instructions closely: keep the site clean, apply any prescribed ointments, avoid picking or stretching the wound, and protect it from sun exposure. A healthy diet and hydration also support faster healing.

A biopsy removes only a small tissue sample to confirm diagnosis, while an excision removes the entire skin cancer along with a margin of healthy tissue to ensure complete removal.

Many patients can shower within 24 hours as long as they avoid soaking the area and gently pat it dry. Dr. Hedayati may give specific instructions based on the size and location of your excision.
