Differentiating between a normal mole and a possible skin cancer symptom often involves paying attention to certain visible changes on the skin. Doctors commonly use the ABCDE rule to help identify warning signs.

A – Asymmetry:
A normal mole usually has a symmetrical shape. If one half of the mole looks different from the other, it may need medical attention.

B – Border:
Benign moles typically have smooth and even borders. Irregular, blurred, or jagged edges could be a warning sign.

C – Color:
Most normal moles are a single shade of brown. If a mole has multiple colors such as black, red, white, or blue, it should be examined.

D – Diameter:
Moles larger than about 6 mm (roughly the size of a pencil eraser) may require evaluation, especially if they continue to grow.

E – Evolving:
Any mole that changes in size, shape, color, or begins to itch, bleed, or crust over time should be checked by a healthcare professional.

In addition, a sore that does not heal, a new dark spot, or a rapidly changing skin mark can also indicate a possible skin cancer symptom. While many skin changes are harmless, it is always safer to consult a doctor if something looks unusual or continues to change.
