Suzanne D. Conzen, M.D., is a Professor in the Department of Internal Medicine at UT Southwestern Medical Center and Chief of the Division of Hematology and Oncology. She specializes in the diagnosis and treatment of breast cancer.

Originally from New York City, Dr. Conzen holds a bachelor's degree in political science from Brown University in Providence, Rhode Island, where she graduated magna cum laude. She earned her medical degree at Yale School of Medicine in New Haven, Connecticut, and completed internal medicine residency training at New York Hospital-Cornell Medical Center in New York City. She then received advanced training in hematology and medical oncology through a clinical fellowship at Dartmouth-Hitchcock Medical Center and in molecular oncology through a research fellowship at Dartmouth Medical School in Bedford, New Hampshire. She also holds a master’s degree from the London School of Hygiene & Tropical Medicine.

Certified by the American Board of Internal Medicine in medical oncology, Dr. Conzen joined the UT Southwestern faculty in 2019.

Dr. Conzen is on several committees at UT Southwestern, including the Clinical Pathways Committee at the Simmons Comprehensive Cancer Center, the Strategic Operations Committee for the Division of Hematology and Oncology, the Internal Promotions and Tenure Committee for the Department of Internal Medicine, and more. 

An established physician-scientist with multiple National Cancer Institute grants, Dr. Conzen focuses her lab’s research on the role of the glucocorticoid receptor in prostate, breast, and ovarian cancers. Her previous research at the University of Chicago led to the recognition of a role for glucocorticoid receptor signaling in breast cancer biology and, more recently, in cancer progression and therapy resistance in prostate and ovarian cancer. She also receives peer-reviewed funding from the Breast Cancer Research Foundation. She has published countless academic articles, contributed chapters to several books, and delivered scores of presentations.

Dr. Conzen has served as senior editor of Cancer Research and as Chair of the National Institutes of Health’s Cancer Etiology Study Section.

In 2006, Dr. Conzen was elected to the American Society for Clinical Investigation. She was elected to the Association of American Physicians in 2020. She is also a member of the American Society for Clinical Oncology, the American Association for Cancer Research, the American Association for the Advancement of Science, the American Society for Molecular Biology and Biochemistry, and the Endocrine Society.
