Description
Moles can appear anywhere on the skin, alone or in
groups. Their colors can range from light brown to red,
blue, dark brown, gray and even black. They may be flat,
slightly raised, smooth, rough and may contain dark
hairs. Most moles are referred to as benign nevi and
are harmless. The term dysplastic nevus refers to moles
that contain abnormal or atypical cells. These dysplastic
nevi have a greater potential for becoming a skin cancer.
The life cycle of the average mole is about 50 years.
Cause
Everyone has moles. Over time, they usually enlarge
and some may develop hairs. As time passes, moles can
slowly change, becoming raised or change color. Some
will not change at all.
