There are 8 different kinds of nipples. Which do you have?

We’re all pretty familiar with our breasts – the size, the feel, how much they are drooping, which bra we need to wear with which outfit – but how familiar are you with your nipples?

There are 8 different types of nipples considered “normal” and Seventeen magazine has illustrated each of them in order to encourage all women to become familiar with their breasts, every single part of them.

Facebook doesn’t allowed breasts on the site so a man’s breasts were used to demonstrate an effective breast self-exam. Article continues after this video.

As we all know, the single most effective way of detecting the early stages of breast cancer is for us to regularly examine our breasts, noting any changes to our breasts and the tissue under our arms, however we often forget to keep an eye on our nipples.

1. Protruding nipples are raised and point outwards. For those of us without any discernible nipples to speak of you can buy those stick on ones.

2. Flat nipples don't have any raised part and blend into the areola but can be stimulated to protrude if needed.

3. Puffy nipples involved puffy areolas and nipples blended together.

4. Inverted nipples are those where the nipples are positioned inward and can't usually be stimulated to protrude.

5. Unilaterally inverted nipples means one is raised and the other is inverted which is perfectly safe and normal if that's the way they have always been.

6. Bumpy nipples are when your nipples and areolas have small bumps. These bumps are called Montgomery glands and sometimes look like whiteheads.

7. Hairy nipples appear when dark, stray hairs grow around the nipples and they are safe to pluck out. Some have more than others and that's totally fine.

8. Supernumarary is when there is an extra nipple normally referred to as a "third nipple" and often appears as a bump.

The thing to remember is that each of these 8 types of nipples is normal. The only time you should be concerned is when there is an unusual change.

Get to know your breasts, your areolas and your nipples and see a doctor if you notice any changes whatsoever.
