Evaluation, monitoring, and removal of common and atypical moles.
Atypical moles, also called dysplastic nevi, look somewhat different from common moles -- often larger, with irregular borders or uneven color. Having several atypical moles increases lifetime melanoma risk, which is why regular dermatologic monitoring is especially important for these patients.
A combination of genetics and cumulative sun exposure; a strong family history of atypical moles or melanoma raises individual risk further.
Consistent sun protection and avoiding tanning beds can help limit the development of new atypical moles.
Routine dermatologic monitoring, often with photography to track changes over time; biopsy or removal for any mole showing concerning features.
Myth: An atypical mole is the same as melanoma. Fact: Atypical moles are benign, but they are a marker of higher risk and need closer monitoring than typical moles.
For a baseline full-body skin exam if you have several atypical-looking moles, and for annual monitoring after that.
