What is the first treatment for basal cell carcinoma?

Basal cell carcinoma is a skin cancer that usually grows locally. Excision removes the visible lesion with a planned margin, and the removed tissue can be examined to check whether the edges are clear. The most suitable approach depends on the body site, tumour size, borders, depth, previous treatment, and the effect of preserving nearby skin. Mohs surgery may be considered in selected high-risk or cosmetically sensitive areas because tissue is checked during the procedure.

Do not pick, cut, or treat a suspicious spot with a home product. A dermatologist may confirm the diagnosis with a biopsy or review existing pathology before recommending treatment. Depending on the findings, options can include surgical excision, Mohs surgery, topical imiquimod, photodynamic therapy, or radiotherapy. These alternatives are not interchangeable; some are reserved for specific superficial, recurrent, high-risk, or surgery-limited situations.

Arrange prompt assessment for a sore that repeatedly bleeds, crusts, fails to heal, becomes shiny or pearly, or changes at the edge. Seek earlier specialist review for a lesion near the eye, nose, ear, lip, or another functionally important area, or for a spot that has returned after treatment. Urgent care is appropriate for heavy bleeding that does not stop with firm pressure.

Ask whether the diagnosis has been confirmed, what risk features are present, and why excision or Mohs surgery is recommended. Discuss the expected scar, wound care, pathology review, and whether another treatment would be safer or more suitable for the lesion’s site.
