Excision is a surgical procedure with potential complications like any other surgery. It is very important to understand the risks before you proceed with the excision.
Biopsy is a test to get more information about suspicious or unusual-looking skin lesions. The results of a biopsy enable your doctor to decide if further treatment is required, and what the best type of treatment will be. Punch biopsy involves cutting a circular piece of skin using a round blade. If the diameter of the punch is 3mm or less, stitches usually are not required.
