Roundup: Genetic links to breast cancer, Avandia under attack, death and the drug official, and more

More genetic links for breast cancer — Whole-genome association studies that tease out links between minute genetic variations and the likelihood of disease are definitely building momentum. Over the last several days, researchers reported six new variations that increase the risk of breast cancer for women who have inherited them. (For background, see this Boston Globe piece or my recent take on the subject.) It’s now conceivable that scientists may soon have an excellent handle on the genetic contributions to this particular disease.
