There are many moles that may appear on the skin. Moles that might be cancerous need to be removed for a biopsy. These moles may be irregularly shaped, bleeding, crusty, or discolored. Other moles, like large or bumpy lesions, are not usually a medical problem; however, they may be unattractive if it's in a highly visible area, like your face. If you have a mole that is irritating, makes you feel self-conscious, or causes other negative emotions, make an appointment with Dr. Calvin Williams to get more information about lesion and mole removal.
