Asymmetry - Melanoma
The ABCD's of Melanoma

Asymmetry is one sign that a mole is not normal. A lesion is asymmetric if half of the mole does not match the other in size, shape, color, or thickness. In this picture of melanoma, you can see that the left side of the lesion is much thicker than the right side.

Other atypical features of this mole include:

  • Border - Even though the border is distinct throughout the lesion, the border on the top half is scalloped and notched.
  • Color - The color is inconsistent. The left side is black and the right side is brown.
