My daughter was in 5th or 6th grade when her breast started bleeding. I took her to an OB/GYN and they said it was normal
when they are going through puberty. She doesn't have it anymore. She still is only having a couple menstral cycles a year though and she's in 9th grade.
Dear Motherhen, Bleeding from the nipple is a symptom that should be evaluated. The cause of bleeding can be from benign conditions such as a papilloma (a wart-like growth in the duct of the breast), however, bleeding could also be a sign of malignancy - although this is rare. It is best to have this further evaluated.
