The annual San Antonio Breast Cancer Symposium (SABC) is a multidisciplinary conference that covers basic molecular and cellular biology, epidemiology, diagnosis and treatment of all types of breast cancer and premalignant breast disease. In 2012, this meeting was held at the Henry B. Gonzalez Convention Center in San Antonio, Texas, United States, from 4 to 8 December.

The symposium consisted of lectures within six general sections covering a range of topics in breast cancer research. These included discussions on research of breast cancer posters, a large number of specialist sessions, and several minisymposia. The report below describes much of the research presented in those general lecture sessions.

The abstracts of all papers and posters presented at this conference have been published in Cancer Research as a supplement: Cancer Research (2012) 72(24), 1s–608s.
