Moles are small collections of specialized pigment cells, called melanocytes, under the skin. All of us have several moles, and they are almost always benign. They can occur anywhere on the skin, including the genitals like you describe.
Rarely, moles may transform into a serious form of skin cancer called melanoma. For this reason, it is important to have any new moles or changing moles checked out by a doctor
, either your primary care doctor
or a dermatologist
In general, the characteristics of a mole that makes it more likely to be worrisome for cancer include: 1. Size greater than about the head of a pencil eraser; 2. Irregular borders or asymmetric look to the mole; 3. Variable color of the mole; 4. Raised elevation of the mole.
I would suggest that you follow back up with your OB GYN doctor, or another primary care doctor, as you are already planning to do. They can take a close look at the moles that you have to make sure that they do not exhibit any of these worrisome characteristics. If so, they may refer you for a biopsy to rule out a skin cancer.
