Vulvar melanoma is a type of vulvar cancer that can begin with the change of a mole that has been present for many years.
The ACS discusses the ABCDE rule that is used to help distinguish a normal mole from a mole that could be malignant.
Asymmetry: 1/2 of the moles do not match the other moles.
Irregular border: The edges of the mole are grooved or notched.
Color: The color on the mole can vary, with different shades of tan, brown, or black, and sometimes patches of red, blue, or white.
Diameter: The mole is more than 6 mm or about 1/4 inch wide.
Growing: Changes in size, shape, or color.
