Smoking May Increase Late Effects Of Radiation For Breast Cancer

Medscape (12/15, Osterweil) reports that “the risks for late lung cancer and ischemic heart disease among women who undergo irradiation for breast cancer are both reassuringly low, unless the patient is a smoker who just can’t kick the habit, said investigators from the Early Breast Cancer Trialists’ Collaborative Group.” The findings were presented at the San Antonio Breast Cancer Symposium. Carolyn Taylor, MD, said, “In our data, the main risks of breast cancer radiotherapy were cardiac mortality and lung cancer, and in nonsmokers, even taking those two risks together, the overall absolute risk was well under 1%, and that’s good news for many women.” However, Dr. Taylor said, “for one specific group of women – that is, long-term smokers who continue to smoke after their radiotherapy – the [absolute] risk of lung cancer may be a few percent, and that’s because the risk of lung cancer is 20 times greater in a smoker than in a nonsmoker.”
