If you or your dermatologist spot a suspicious-looking mole or freckle, your doctor may order a biopsy. In this process, a doctor will cut out a small section of it or remove the spot entirely and then send the tissue sample to a lab for testing. The biopsy helps detect the presence of skin cancer, as well as what type of skin cancer you may have.
There is a small risk of scarring with a biopsy. If you are diagnosed with skin cancer, your dermatologist may recommend additional testing, which can help determine the stage and extend of the disease.
