Can I remove the nevus on my mammary areola?

See a derm surgeon and he/she will tell you what it is and how to remove it and probably do it right then and there easily under local.

I recommend getting a formal evaluation with a cosmetic dermatologist. Moles can be removed with laser, radiowave or shave. See an expert. Best, Dr. Emer

The areola is covered by skin and this skin can be treated in the same way as skin over other parts of the body. A mole on the areola can be surgically removed as with a mole elsewhere. It is important that an accurate diagnosis is made. Abnormal moles can be serious as on other parts of the body. I suggest you seek the opinion of a suitably qualified and experienced plastic surgeon.Best wishes.
