An itching mole can be a sign of a melanoma, or cancerous skin growth, but the vast majority of moles are harmless. If a new or existing mole changes shape or begins to itch, ooze, bleed or becomes tender, it is important to have it evaluated by a doctor, according to WebMD. While melanoma can occur in existing moles, it is more common in new skin growths.

According to WebMD, it is important to take note of any moles that change over the course of a few weeks to a month. Things that are important to look for include changes in size, color and shape as well as the development of symptoms such as burning or itching.

During an appointment for an itching mole, a doctor takes a medical history and physically examines the mole as well as any other moles on the body, according to WebMD. If necessary, a biopsy of the mole's tissue is taken for examination in a laboratory. If desired, the mole can be removed for cosmetic reasons regardless of the prognosis. If the mole is cancerous, early detection and removal is important to prevent the cancer from spreading to nearby tissues and organs. Most moles can be easily and quickly removed in a doctor's or dermatologist's office.
