In its most general form, a nipple is a structure from which a fluid emanates. More specifically, it is the projection on the breasts or udder of a mammal by which, in females, breast milk is delivered to a mother's young.

When doing your monthly breast self-exam, you may discover persistent bumps or lumps on or just beneath your nipple or areola. If you do, see your doctor in order to find out what's causing these lumps.
