How effective is surgical excision for squamous cell carcinoma?

The surgeon removes the visible carcinoma with a margin of nearby skin. A laboratory examines the specimen and checks the edges. Clear edges support complete local removal; involved or narrow edges may lead to discussion of another excision or a different treatment. The tumour's depth, growth pattern, location and the person's immune health can affect the plan.

Excision addresses the treated lesion, but it does not remove the possibility of another skin cancer. A scar, temporary altered sensation or wound-healing problem can occur, and reconstruction may be needed when the defect is larger or lies in a delicate area. See [Squamous Cell Carcinoma](/conditions/squamous-cell-carcinoma/) and [Surgical Excision](/treatments/surgical-dermatology/excisional-surgery/).

Before surgery, provide a full medicine list and mention blood-thinning treatment, immune suppression, allergies and previous difficulty healing. Ask how the edges will be assessed and when the pathology report will be discussed. Keep the wound protected, follow dressing instructions and avoid pulling or soaking it until advised. Attend skin checks because sun-exposed skin can develop additional suspicious areas.

Contact the surgical service for bleeding that persists despite pressure, increasing pain, spreading redness, pus, fever or wound separation. Seek prompt review for a sore, crusted patch or firm bump that grows, bleeds or fails to heal, including near the treated scar. Report new numbness, weakness or a tender lump nearby rather than waiting for the next routine visit.

Ask: What risk features does my carcinoma have? What margin and closure do you recommend? How will the specimen edges be checked? When will I get the pathology result? Could further treatment be needed? How often should I have full-skin examinations, and what sun-protection steps fit my routine?
