Do you need Mohs surgery after a skin biopsy?

A biopsy removes a sample for laboratory examination. The report may describe a benign growth, a precancerous change or a skin cancer, and may comment on whether the sampled tissue appears fully removed. The result is interpreted alongside the examination and the exact site of the lesion.

Mohs surgery removes visible tissue in stages while checking the edges during the procedure. It may be considered for selected cancers where conserving healthy tissue matters, where the tumour has features that make edge control useful, or where the site is cosmetically or functionally sensitive. Other surgical or non-surgical treatments may be appropriate.

Obtain a copy of the pathology report and ask the treating clinician to explain the diagnosis, margins and treatment options. Tell them about previous skin cancers, immune-system medicines, blood thinners, allergies and healing problems. If Mohs is recommended, discuss the expected wound, reconstruction options, appointment-day process and aftercare.

Keep the biopsy site clean and follow the wound instructions. Do not delay follow-up while waiting for the area to look different; the next step depends on the report and clinical plan.

Contact the clinic promptly for bleeding that does not stop with firm pressure, spreading redness, increasing pain, pus, fever, wound separation or an allergic reaction. Seek urgent care for uncontrolled bleeding, severe swelling or breathing difficulty. A changing, bleeding or non-healing lesion elsewhere also deserves assessment.

What exactly did the biopsy show? Were the edges clear? Why is Mohs preferred for this site and diagnosis? What alternatives are reasonable, and who will manage wound closure and follow-up?
