What's the difference between a mole and a birthmark?

Hello, birthmarks usually appear in pigment blocks. Moles are rare, generally convex, mostly black or brown, and a few are long hair. In fact, they all belong to the category of birthmarks. Their incidence is about 10%, most of them will not disappear by themselves, and some will even cause lesions in the future. It is better to go to the hospital as soon as possible to check for the possibility of lesions. I hope I can help you.
