New Evidence Linking Smoking to Increased Risk of Breast Cancer

Posted on March 19, 2014

Post-menopausal women who smoke or have smoked in the past may have an increased risk of breast cancer compared with women who have never smoked. The authors confirmed this association in over 186,000 women enrolled in the NIH-AARP Diet and Health Study, of whom about 7,500 developed invasive breast cancer during almost 10 years of follow-up. A major strength of the study was that the authors were able to control for alcohol consumption, which is known to increase the risk of breast cancer, and is more common among smokers.
