Antibiotic Use Linked With Breast Cancer Risk

The use of antibiotics appears to be associated with an increased risk of breast cancer and fatal breast cancer, according to the results of a new study reported in this week's issue of the Journal of the American Medical Association. However, the investigators add that although a relationship has been found, their findings do not prove that antibiotic use is the cause of breast cancer in these women and they note that other factors may be involved.
