We recommend visiting an experienced dermatologist when you spot a mole that features one or more of the following ABCDE warning signs:
A = Asymmetry: when one half of a mole or mark is different from the other half
B = Border: the edges of the mole or mark are scalloped, uneven, notched, or irregular
C = Color: the mole or mark is not a uniform color throughout; it can be different shades of the same color, or pink, red, or white in a spot that is otherwise brown or black
D = Diameter: if the mole or mark is 6 millimeters (about the size of a pencil eraser) or larger, it could be a melanoma, BUT it’s also possible for melanoma to be smaller than 6 mm
E = Evolving: the mole or mark is changing in size, shape, color, or texture
However, for melanoma skin cancer specifically, it’s important to note not all melanomas show these warning signs, but if you do notice any of them, schedule an appointment with a dermatologist immediately.
