BOSTON, Oct. 29, 2012 (GLOBE NEWSWIRE) -- Elderly women with early-stage breast cancer who received adjuvant radiation therapy after lumpectomy surgery have improved cause-specific survival (CSS) compared to those patients who underwent surgery alone, according to research presented today at the American Society for Radiation Oncology’s (ASTRO’s) 54th Annual Meeting. Additionally, the data suggests that patients who have a life expectancy of at least 10 years after diagnosis and treatment benefit in local tumor control and in overall survival if they receive adjuvant radiation therapy.
