Your doctor will examine your skin and may remove a small, abnormal piece to be examined in a laboratory. This procedure is called a biopsy. Occasionally, the doctor will remove the entire abnormal area.

In the laboratory, a pathologist will examine the tissue under a microscope to determine if it is a skin cancer. If so, the pathologist will look at the margins (edges) of the specimen. If cancer remains at the margin, you will need another procedure to remove the rest of the cancer.
