There is no one best method to treat all skin cancers and precancers. The choice is determined by many factors, including the location, type, size, whether it is a primary tumor or a recurrent one, the health and preference of the patient, and the physician’s experience with the technique. For example, a treatment that has a high cure rate and is painless but leaves a large scar might be acceptable for a tumor on the body, but not on the face.
Almost all treatments can be performed in the physician’s office or in a special surgical facility. Most skin cancer removal can be done using a local anesthetic. Rarely, extensive tumors may require general anesthesia and hospital admission.
