A variety of techniques, from relatively simple biopsies to more complex surgical excisions, may be used to to remove skin lesions that range from benign growths (such as an unsightly mole) to a malignant melanoma. Physicians may remove a lesion to make sure it is not cancerous. (If it proves to be cancerous, it may be removed to prevent spreading.)

Most of the procedures are not highly invasive and are often well tolerated by young and old patients and those with other medical conditions.
