Girls' Cancer Treatments Hike Breast Cancer Risk

...by as much as 7 times

(Newser) – The powerful therapies used to treat cancer in girls drastically increase their odds of suffering breast cancer as adults—by as much as six or seven times, a study finds. For most women, the odds of getting breast cancer by age 50 are about 4%. Among women who received chest radiation as kids, however, it's 24%, while women who were treated for Hodgkin lymphoma face a 30% risk, USA Today reports.

That's far higher than the 10% risk among women with mutations in the BRCA2 gene, and it approaches the 31% risk among women with mutations in the BRCA1 gene—mutations that sometimes prompt women to have ovary removals or mastectomies. The study reviewed 1,268 women between 1970 and 1986, the Wall Street Journal notes, and the breast cancer risk may increase as subjects get older. In short, "cure is not enough," says an expert.

Well daaa. I have known this for decades. Just didn't have these numbers. One of my sisters had Hodgkin lymphoma in 1977 when she was 13 yo. I remember warning her a about 10 years later she was at high risk for more cancer because of the treatments. It was like nobody had told her before. She died in 1997 of breast cancer. I wonder how much money was wasted on that study of what is so obvious.
