Had a small raised mole checked (dr says it looks fine) is it still necessary to remove it or better to just let it be. if removed, will it grow back?

Monitor mole: Hello, There are many different types of moles, and most are fine. That said, any changes in an existing mole, or new moles as an adult can represent a possible melanoma. Since melanomas are the most dangerous type of skin cancer, it is always best to have any mole in question checked by a conscientious dermatologist and possibly biopsied.
