When is Mohs surgery recommended for squamous cell carcinoma?

Squamous cell carcinoma is a skin cancer arising from squamous cells. Mohs surgery removes the tumour in carefully mapped stages. The surgeon examines the edges of each layer during the procedure and removes another layer only where tumour remains, when appropriate for the case.

Your clinician considers the pathology report, tumour size and depth, exact location, border definition, growth pattern, recurrence and your general health. Lesions on the face, ears, lips, hands or other sensitive sites may need a tissue-sparing plan. Mohs is one possible treatment, not an automatic choice for every lesion.

Book a dermatology consultation and bring the biopsy report, medicine list and history of earlier procedures. Avoid picking a crust or applying unrequested products to the site. Ask how the diagnosis affects timing, whether Mohs or another treatment is more suitable, and what repair and wound care would involve. See [Squamous Cell Carcinoma](/conditions/squamous-cell-carcinoma/) and [Mohs Surgery](/treatments/surgical-dermatology/mohs-surgery/) for background.

Seek dermatology review for a growing rough or scaly lesion, a sore that repeatedly bleeds or crusts, a tender thickened patch, or a wound that does not heal. These features need examination and do not by themselves confirm cancer. Following surgery, contact the clinic about persistent bleeding, spreading redness, drainage, fever, worsening pain or wound separation.

Ask which pathology features make the tumour high risk, why Mohs is preferred, what alternatives exist, how tissue edges will be checked, and whether reconstruction is likely. Clarify anaesthetic, expected wound appearance, aftercare, activity changes and follow-up visits.
