Study: Breast Cancer Rates Rising in Young Women
A new breast cancer study, published in the Journal of the American Medical Association, is leaving researchers puzzled.
FOX News Radio’s Lisa Brady explains why:
Breast cancer is still considered uncommon in women under age 40, hence that threshold for screening guidelines. ¬†So researchers comparing 1976 to 2009 were surprised to find a small, but significant increase in advanced cases of breast cancer in women ages 25-39.
(Dr. Pederson) “It can present at a much later stage and be much more deadly.”
…Dr. Holly Pederson at Cleveland Clinic – not part of the study, led by researchers in Washington state who say there’s probably more than one reason. ¬†Theories range from population and lifestyle changes to later pregnancies and hormone use, perhaps spreading a tumor more quickly. ¬†For now, no one knows for sure.
