Skin moles rarely cause symptoms.
The normal appearance of a skin mole includes:
- Skin lesion colored tan, brown, or black
- Skin lesion has smooth, sharp borders
- Skin lesion is round or oval shape
- Skin lesion is less than 6 mm (1/4 inch) in diameter
- Symmetric: one side has the same shape as the other
Skin moles have characteristics that are different from melanoma, a serious form of skin cancer.
