This means looking over your entire body including your back, your scalp, soles of your feet, between your toes, even the palms of your hands. If there are any changes in the size, color, shape, or texture of a mole, the development of a new mole, or any other unusual changes in the skin, see your dermatologist immediately. Follow the simple ABCD rule which outlines the warning signs of melanoma. A is for asymmetry. One half of the mole does not match the other half.
B is for border irregularity.
The edges of the mole are ragged, notched, or blurred. C is for color. The pigmentation of the mole is not uniform. Shades of tan, brown, and black are present. Dashes of red, white, and blue add to the mottled appearance.
