How effective is skin cancer surgery for squamous cell carcinoma?

The surgeon removes the visible growth with a margin of nearby skin. Mohs surgery may examine edges during treatment, helping preserve healthy tissue while checking that cancer cells are not left behind. The result depends on depth, size, location, growth pattern and whether the tumour has reached nerves or lymph nodes.

Healing can leave a scar, and larger defects may need reconstruction. Follow-up matters because squamous cell carcinoma can return at the treated site or arise elsewhere on sun-exposed skin.

Ask which operation is suitable, how much skin may be removed and whether pathology will confirm clear margins. Share every medicine, including blood thinners and supplements. Follow wound-care instructions, protect the area from sun and attend skin checks. Report a wound that opens, becomes increasingly painful or produces pus.

Arrange prompt assessment for a sore, scaly patch, wart-like growth or wound that does not heal, especially if it bleeds, becomes tender or enlarges. After surgery, seek urgent advice for uncontrolled bleeding, spreading redness, fever, severe pain or new weakness near the treated area.

Ask whether pathology shows clear margins, whether Mohs is appropriate, what monitoring you need and how the scar may be managed.
