How common is changing mole in atypical mole?

An atypical mole may be larger or less uniform in colour, shape, or border than an ordinary mole. It can show gradual variation over time, while a concerning change may involve growth, a new area of dark or uneven colour, an altered edge, or a change in texture.

A changing mole does not identify its cause by appearance alone. Benign moles can change, but melanoma can also present with a changing mole. A clinician considers the whole pattern, your skin history, and comparison with other moles.

Take a clear photograph in consistent lighting with a ruler or another size reference nearby, and record the date and location. Compare images over time rather than relying on memory. Avoid picking, scratching, or trying to remove the mole at home.

Book a skin examination for a mole that is changing, new in adulthood, repeatedly bleeding, or difficult to compare. A clinician may examine it with magnification and decide whether observation, photography, or a sample is appropriate.

Arrange prompt medical review if change is rapid, the mole develops several different colours, the border becomes uneven, or it becomes persistently itchy, tender, crusted, or bleeding. These features warrant examination even when the mole is small.

Seek faster help if a lesion is bleeding without clear injury, forming an open sore, or changing alongside swollen nearby glands or unexplained illness. Do not wait for a photograph to prove that a change is significant.

Does this mole need dermoscopic examination or a biopsy? What exact feature should I monitor? How often should my skin be checked if I have several atypical moles or a personal or family history of skin cancer?
