A dermatologist can remove a mole during an office visit. A few moles will require a second visit. Whether 1 or 2 visits, a dermatologist can safely and easily remove a mole. The dermatologist cuts out the entire mole and stitches the skin closed. If the dermatologist suspects that the mole contains cancer, the dermatologist will send the mole to a lab. It will be examined under a microscope. This is called a biopsy. The dermatologist uses a surgical blade to remove the mole.
