Smoking ups risk with radiation for breast cancer

NEW YORK (Reuters Health) - Cigarette smoking dramatically increases the risk that a woman who has undergone radiation treatment for breast cancer will develop lung cancer later on, a new study shows.

Radiation after mastectomy may be considered for some high-risk breast cancer patients, Dr. Elizabeth L. Kaufman and colleagues from Columbia University in New York City point out in their report. However, radiation can cause many complications, including increasing the likelihood that a patient will develop lung cancer 10 or more years after treatment, they add.
