I have plenty (I can't count them) of little brown dots on my arms (my skin is pale) and I was wondering if they were moles. I'm 100% sure that I don't have skin cancer (I have those since I'm born) so don't give me the "you have cancer" or "go see a doctor" answer. (Sorry if that sounded rude.)
Yes they are moles.
A mole is a common benign skin lesion due to a local proliferation of pigment cells (melanocytes). It is more correctly called a melanocytic naevus (American spelling ‘nevus’), and is sometimes also called a naevocytic naevus. A brown or black mole contains the pigment melanin, so may also be called a pigmented naevus.
A mole can be present at birth (congenital naevus) or appear later (acquired naevus). There are various kinds of congenital and acquired naevi.
