Will a severely atypical mole indicate melanoma on biopsy? I just had second incision and wait for further answers.

Hello,
If the first biopsy showed atypical nevus, it is highly unlikely, although not impossible, that the diagnosis will change.The second procedure likely represent the derms attemp to remove the lesion.

Atypical moles are pre-cancerous growths so they are not melanomas. To be safe and ensure complete removal of these growths, in our office we will do an excision with suture closure
to get clear margins for all moles that have moderate to severe atypia. We also follow all of our
"atypical mole" patients by doing full skin examinations every six
months.You can follow the video link to learn more about identifying the
changes in moles that are suspicious for skin cancer.
