Aspirin Seen Cutting Risk Of Type Of Breast Cancer, National Cancer Institute Study

WASHINGTON (Reuters) - A daily aspirin may give women modest protection against the most common type of breast cancer, U.S. government researchers said on Wednesday. The finding reinforced earlier research indicating regular use of aspirin might reduce the risk of so-called estrogen receptor-positive breast cancer, which makes up about three quarters of breast cancer cases. Researchers led by Gretchen Gierach of the National Cancer Institute, part of the National Institutes of Health, found that women who took aspirin daily cut their risk of developing this type of breast cancer by 16 percent.
