Explore the Triple Negative Breast Cancer Program


The Triple Negative Breast Cancer Program at the Massachusetts General Hospital Cancer Center was established to provide the best care possible to patients with triple negative breast cancer (TNBC). Our program aim is to provide state of the art, compassionate care to patients with all stages of TNBC, and to advance that care by conducting cutting-edge research. We also aim to enhance care through providing an array of educational and supportive programs and materials.

Over 275,000 patients will be diagnosed with breast cancer in 2020. Approximately 15% (over 40,000) will be triple negative breast cancer which is a type of breast cancer that lacks the 3 receptors (or markers) found in breast cancer – Estrogen Receptor, Progesterone Receptor, and HER2. This type of breast cancer is more common in younger women, underserved populations, and is associated with genetic alterations in the BRCA1 breast cancer gene. The TNBC Program at the Mass General Cancer Center was founded in 2018 with generous philanthropic support to develop more effective treatments and improve outcomes, education, and quality of life for patients with TNBC.

Innovative Approaches

Our collaborate team of physicians and researchers work together to bring the latest advances in TNBC care into our clinic.

  • World class physicians with the tools to treat you with cutting-edge therapies
  • Large network of supportive services to care for you and your family
  • Clinical trials focused on novel therapies for TNBC

Multidisciplinary Patient Care

The Mass General Cancer Center is proud to be home to some of the leading experts in breast oncology. Our medical, surgical, and radiation oncologists work together to create a plan that fits your life and addresses your specific health needs. Our multidisciplinary team meets each day to discuss all newly diagnosed patients and create a plan that is personalized to you.

Clinical Trials

The Mass General Center for Breast Cancer offers an extensive array of clinical trials for patients with breast cancer. Triple negative breast cancer remains an unmet need, and many new trials are focused specifically on treating TNBC. The TNBC program can help you navigate which trials you may be eligible for. Clinical trials are available to TNBC patients at all stages of disease.
