A skin biopsy is a procedure in which a sample of skin tissue is removed, processed, and examined under a microscope. Several different methods may be used to obtain a skin sample, depending on the size and location of the area of skin. It’s a quick, simple procedure.
We use local anesthetic and take a small tissue sample, which is then examined under a microscope. The purpose is to diagnose the condition, not treat it, so once the biopsy site heals up, if the biopsy revealed skin cancer, the remainder of the growth will be removed. If any atypical cells are found, they will be removed if deemed necessary, or the doctor might photograph them and have you come back weeks or months later to see if they have grown or changed in any way.
