Does melanoma cause a changing mole?

Change can involve size, shape, colour, border, or surface. A mole may become more asymmetric, develop several shades, form an uneven edge, or gain a scaly, crusted, raised, or bleeding surface. Some changes are subtle and easier to spot when you compare a current image with an earlier one. Normal skin changes, irritation, hormonal shifts, or an injured mole can also alter appearance, so visual pattern alone cannot confirm melanoma.

Take a clear photograph in good light and include a simple size reference. Avoid picking, scraping, or applying harsh products to the mole. Book a dermatology assessment for a new or changing mole, especially when the change continues, differs from nearby moles, or has symptoms such as itching, crusting, or bleeding. Bring older photographs and a list of when you first noticed the change.

Seek prompt review for rapid enlargement, a strongly uneven outline, multiple colours, spontaneous bleeding, an open sore, or a dark area spreading beyond the original mole. A change that is persistent deserves review even when it is not painful. Urgent care is appropriate for uncontrolled bleeding or signs of a significant infection.

Ask what specific feature has changed, whether dermoscopy is needed, and whether the mole should be monitored or sampled. Ask how to track it at home and which new symptoms should bring your appointment forward.
