October 1, 2025- For more than 40 years, Mayo Clinic has been at the forefront of breast cancer innovation, transforming a once-limited diagnosis into a story of record survival rates, groundbreaking therapies and renewing hope for millions of patients worldwide.
Mammography revolutionized breast cancer care in the 1980s by finding tumors earlier, making them more treatable. Advances in digital mammography and 3D tomosynthesis have since improved accuracy, reduced false alarms and revealed cancers hidden in dense breast tissue.
Genetic testing has also reshaped care. Discoveries of BRCA1 and BRCA2 mutations — and later, additional genetic markers — have allowed healthcare teams to personalize screening and prevention. Mayo Clinic Comprehensive Cancer Center researchers, such as Siddhartha Yadav, M.B.B.S., M.D., and Fergus Couch, Ph.D., have helped refine risk predictions so patients and care teams can make more informed choices about surgery, surveillance or medication.
