Moles, or nevi, are collections of pigmented cells, called melanocytes, in the skin. They are usually benign but do have a rare chance of transforming into melanoma, a form of skin cancer. Any mole greater than 6 mm in diameter, elevated, with irregular borders or multiple colors, or that is growing asymmetrically should be evaluated by your doctor
. Most people have a few dozen moles at most on their body. Rarely, some people have hundreds of moles. This can be part of a genetic condition called dysplastic nevus syndrome. People who have this syndrome are at higher risk of the moles transforming into skin cancer, and they should be evaluated closely and regularly by a dermatologist
for any signs of this transformation. As always the diagnosis and the management of your particular skin concerns will require a physical examination by your personal physician. Setting up an office visit with your primary care doctor
or your dermatologist is highly recommended.
