SG-BCC 2027, the 20th St.Gallen International Breast Cancer Conference, runs 17 to 20 March 2027 at the Austria Center Vienna, organised by the Foundation St.Gallen Oncology Conferences (SONK). The congress is the professional meeting point for oncologists, breast surgeons, radiologists, pathologists, researchers and patient advocates working in early breast cancer, held in Vienna (Vienna Tourist Board), the conference's host city since 2015.
The scientific programme runs four days, Wednesday 17 to Saturday 20 March 2027, and closes at lunchtime on the Saturday, per the programme overview.

Thursday evening is the ticketed Official Conference Evening at the Museum of Applied Arts Vienna (MAK), a different venue across town, with a formal dinner and an exclusive exhibition visit. The congress closes on Saturday morning with the St.Gallen International Breast Cancer Consensus Session, where about 80 international panellists set guidelines the conference chair says will influence clinical practice in over 150 countries. CME accreditation is pending for 2027.
