Moles are spots of pigmented skin that are black, brown or red in colour. In fact, they occur due to the excess production of pigmented skin cells or melanocytes.
Most moels don’t need treatment. However, if your doctor suspects that a mole is cancerous, he do a biopsy of that mole.
Most moles are benign and do not need to be treated unless it interferes with basic functioning or seems unsightly.
