Border - Normal Mole
The ABCD's of Melanoma

A normal mole has well-defined, regular borders. In this picture, even though the mole is a darker color, the border between mole and normal skin is distinct and consistent -- not ragged or scalloped.

Other normal features of this mole include:

  • Symmetry - If you cut this mole in half, each halve would have the same color, shape, and thickness.
  • Color - This mole is a consistent brown throughout.
