The study just published inthe Journal of the American Medical Association found the incidence of advanced breast cancer in women ages 25 to 39, rose 2.9 percnet over the last three decades.
Dr. Linyee Chang, with St. Charles Cancer Center, says an increase is concerning.
"To be alarmed by the study would be an overreaction. But it does highlight the importance of controling the risk factors you can and seeking attention when something doesn't feel right or seem right."
Dr. Change says we don't know what's behind the slight increase in breast cancer in young women, but she suspects environmental or lifestyle factors may be to blame. She says more study is needed.
