Wide local excision:
Wide-local excisions are often used for basal cell carcinomas or squamous cell carcinomas, especially those which have recurred, and for malignant melanomas. The initial treatment for a suspected melanoma is to cut out (excise) all of the melanoma cells. When the lesion is first removed, we do not know for sure if it is a melanoma or not, and if it is a melanoma how thick it is, so the excision is usually done with narrow margins (the area of normal skin around the suspected melanoma). The specimen that is cut out from the skin is sent to a laboratory, so that a pathologist can examine it under the microscope. Pathologists look to see if what has been removed is a melanoma and how thick it is.
