About SABCS

Since its inception in 1977, San Antonio Breast Cancer Symposium (SABCS) has grown to a program that covers the latest research on the experimental biology, etiology, prevention, diagnosis, and treatment of breast cancer and premalignant breast disease. The Symposium is attended by a large international audience of researchers, health professionals, physicians, oncologists, and those with a special interest in breast cancer from over 90 countries.

To complement the clinical focus of the annual SABCS, Baylor College of Medicine became a joint sponsor of SABCS in 2005. Additionally, the Cancer Therapy & Research Center (CTRC) at UT Health Science Center San Antonio and American Association for Cancer Research (AACR), a prestigious scientific organization known for its basic, translational and clinical cancer research, began collaboration with SABC in 2007. The Symposium was renamed the CTRC-AACR San Antonio Breast Cancer Symposium.
