Following 8,894 Icelandic men for 24 years, Johanna Torfadottir's team found men who drank milk daily as teenagers but stopped later were three times as likely to be diagnosed with advanced prostate cancer. The study is observational and proves no cause.

Disease
Sex hormones linked to breast cancer risk
Testing blood from 265 breast cancer cases and 541 controls in the Nurses' Health Study, researchers found each elevated sex hormone carried about 16% higher risk, and women in the top fifth for estrogens or androgens were twice as likely to have breast cancer.
Drug
Estrogen plus progestin more dangerous than thought
Rowan Chlebowski's team reported in JAMA that women who used estrogen plus progestin for an average of 5.6 years were 25 percent more likely to develop breast cancer and twice as likely to die from it, over follow-up running through August 2009.
Miscellaneous
Jane Fonda diagnosed with non-invasive breast cancer
Fonda told Entertainment Tonight that a routine checkup found a small breast tumor a few weeks earlier, that the disease was non-invasive, and that surgery removed it and she is now cancer free. At 72 she is promoting new fitness DVDs.
Drug
Unsafe at any dose: Hormone therapy boosts cancer death risk
A JAMA report finds hormone therapy raises the chance of dying from breast cancer, not only of developing it; the estrogen-plus-progestin combination was already tied to a 26 percent higher risk. An accompanying editorial questions even the lowest-dose, shortest-time advice.
Cancer
Breast Cancer Risk: One Size May Not Fit All
USC researchers tracking 3,000 women from 1995 to 2006 found 15 years or more of estrogen therapy raised breast cancer risk 19%, and estrogen with progestin raised it 83%. Thinner women faced greater post-HRT risk than obese women, which the team did not explain.
