It is worth noting that the vast majority of atypical moles will never become malignant.

However, numerous studies indicate that about half of melanomas arise from atypical moles.

When an atypical mole has been identified, a skin biopsy takes place in order to best diagnose it.

Certain symptoms may indicate the development of an atypical mole, which a doctor should check.

Some people have only 1 or 2 atypical moles; some people may have more than 100.

The tendency to develop atypical moles can run in families (inherited predisposition).

The risk is especially high for people with a family history of both atypical moles and melanoma.

For example, you may have abnormal, or atypical, moles.

Having many atypical moles increases your risk of melanoma.

Photographs may be used to document and detect changes in the skin, especially atypical moles.
