BOSTON, Oct. 29, 2012 (GLOBE NEWSWIRE) -- Older women with early-stage, low-risk breast cancer who were treated with radiation therapy (RT) after breast-conserving surgery (BCS) showed higher cause- specific (CSS) and overall survival (OS) rates than those who did not undergo radiation, according to research presented today at the American Society for Radiation Oncology’s (ASTRO’s) 54th Annual Meeting. The study also found a six percent decrease in the use of radiation after 2004 in this population of patients, suggesting that treatment guidelines, which allow for omission of radiation therapy, may need to be re-examined.
