Inverted Nipples at Age 13?

Inverted nipples are caused by tightened breast duct tissue and may be due to a variety of reasons, such as genetics, trauma, pregnancy and lactation. Cancer isn't usually a cause. You can see a doctor for a physical examination if you are concerned. I would wait until you are about 18 or 19 years old before considering corrective surgery. Don't be worried about it, because it's very common.

If you are concerned go see your primary care doctor for a visit. A lot of inverted nipples come out with time. If they dont rest easy knowing surgery is quick and simple
