When to worry about a changing mole if you have melanoma

Changing Mole is a very common presentation of Melanoma. A mole may become uneven, develop several shades, form an irregular edge, enlarge, or stand out from your other marks. It can also itch, bleed, crust, feel sore, or become raised. These features do not diagnose melanoma on their own; harmless moles and other skin conditions can change too. A clinician may examine the whole skin surface and use a magnifying dermatoscope to decide whether the mark needs monitoring or sampling.

Arrange a skin assessment soon if a mole is changing or is new and unusual for you. Take a clear photograph beside a ruler, record when you first noticed the change, and note any itching, bleeding, crusting, or tenderness. Avoid picking the area or applying products that could alter its appearance. Bring details of previous skin cancers, significant sun exposure, and close relatives with melanoma. A clinician may compare the mole with earlier photographs and discuss observation or a biopsy.

Seek prompt medical advice for a mark that changes over a short period, bleeds without being injured, repeatedly crusts, becomes painful, or develops a dark area that was not there before. Ask for faster help if redness or swelling spreads around the lesion, bleeding does not stop with gentle pressure, or you feel unwell. Do not wait for a scheduled appointment if the change is substantial; contact a primary care clinician or dermatology service and explain the specific change.
