Norton notes that the study was not a randomized clinical trial of soy consumption. That is, rather than randomly assigning breast-cancer survivors to consume or not consume various amounts of soy, then following those participants to see whether they developed recurrent tumors, the study looked retrospectively at women's self-determined soy-eating habits. The randomized clinical trial is the gold standard upon which medical practice is determined, and the only kind of trial that gives scientists confidence that other variables are not confounding their results. In the new study, for example, the authors note that the women eating...
...healthy balanced diet is safe. But I would avoid trying to eat a totally soy-based diet or taking a soy supplement. You have to be careful in not extrapolating beyond the study," says Dr. Richard Lee, medical director of the Integrative Medicine Program at MD Anderson Cancer Center in Houston...

...Mammography Guidelines It usually takes a Washington scandal to put the discussion of women's breasts on political agendas, but in November it was a routine update of breast-cancer-screening guidelines by a government panel of medical advisers that stirred up a furor. Based on new calculations weighing the risks and benefits of routine screening, the U.S. Preventive Services Task Force's new recommendations advised women to begin routine mammograms at age 50 instead of 40 and to switch from yearly to biennial screenings; it also advised women to eliminate breast self-exams altogether. Doctors, patients, cancer advocacy groups...
...Prostate-Cancer Screening To screen or not to screen? When it comes to cancer, doctors say early detection is the best defense. But the picture is a little fuzzier when it comes to prostate cancer, which in many cases progresses slowly and may not require aggressive treatment. In March, a 10-year National Cancer Institute study involving more than 76,000 men seemed to make the case for watchful waiting. About half of the study volunteers were randomly assigned to the screening group, getting either a manual exam or a prostate-specific antigen test each year; the latter test measures...
