Can teens develop breast cancer?

Extremely rare: ...But not impossible. The youngest person in the U.S. To be diagnosed was a 10 yr old girl. She presented with an itch of her breast and her mom noticed the lump. http://www.ocregister.com/articles/hannah-317453-cancer-breast.html bottom line, get teen checked by doctor if you are concerned!

Very rare: The best data (surveillance, epidemiology and end results (seer)) i could find was an incidence rate of 0.03 per 100, 000 people in 2003 for malignant breast carcinoma in those under the age of 19. This roughly translates into about 100 new cases in the United States per year.
