H. Ballentine Carter, M.D., is professor of urology and oncology and the director of adult urology at the Johns Hopkins University School of Medicine in Baltimore. He has written extensively on the diagnosis and staging of prostate cancer. In particular, he has performed research on the prostate-specific antigen (PSA) test: how results change as men age; the variability of results in men with prostate cancer; and the test’s use in staging, predicting, and managing prostate cancer.

Dr. Carter chaired the American Urological Association guideline panel that made recommendations for prostate cancer diagnosis. He leads one of the largest active surveillance programs in the United States to monitor men with prostate cancer who do not need immediate treatment. Results from this program have been used to inform guidelines for the management of men with early prostate cancer.

Dr. Carter has had research articles published in a number of publications, including The Journal of Urology, Urology, Cancer Research, The Journal of the American Medical Association (JAMA), the Journal of Clinical Oncology, and the Journal of the National Cancer Institute.
