St. Gallen Guidelines

The St. Gallen Guidelines are a set of evidence-based recommendations used by doctors to decide on breast cancer treatment. They help determine whether a patient needs surgery, chemotherapy, radiation, or hormone therapy based on factors like tumor size, type, and risk of recurrence. Developed by experts at the University of St. Gallen in Switzerland, these guidelines aim to personalize therapy, avoid unnecessary treatment, and improve outcomes, ensuring patients receive the most appropriate care for their specific situation.
