Daily coffee consumption may be associated with reduced breast cancer risk.HealthDay (5/10, Mozes) reported that women who "drink a substantial amount of coffee each day may lower their risk for developing a particular type of breast cancer," according to a study in Breast Cancer Research. The researchers assessed "5,929 Swedish women, aged 50 to 74," half of whom had breast cancer. Drinking coffee "appeared to spur a 'strong reduction' in risk for ER-negative breast cancer." Women who drank "five cups of coffee a day had a 33 percent to 57 percent lower risk for ER-negative cancer than did those who drank less than one cup a day."
However, WebMD (5/10, Doheny) noted that a "US expert warns that the new finding about reduction in risk for ER-negative breast cancer could be due to chance. The only solid message from this study and previous ones, says Shumin Zhang, MD, ScD, a researcher at Harvard Medical School, is this: 'Drinking coffee doesn't seem to increase the overall risk of breast cancer.'"
