Since 1977, the Symposium’s mission has been to provide state-of-the-art information on breast cancer research. From a one-day regional conference, the Symposium has grown to a five-day program attended by a broad international audience of academic and private researchers and physicians from over 90 countries. In 2007, the Cancer Therapy & Research Center (CTRC) at UT Health Science Center San Antonio and the American Association for Cancer Research (AACR) announced a collaboration for the future of the San Antonio Breast Cancer Symposium ®. The Symposium was renamed the CTRC-AACR San Antonio Breast Cancer Symposium. Complementing the clinical strengths of the highly regarded annual San Antonio Breast Cancer Symposium®, the AACR's scientific prestige in basic, translational and clinical cancer research will create a unique and comprehensive scientific meeting that will advance breast cancer research for the benefit of patients.
