Mark Preston, MD, MPH, Awarded $774K Department of Defense Grant

Dr. Preston has been awarded a $774K award from the U.S. Army Medical Research Acquisition Activity for his study:PSA level during midlife and undiagnosed prostate cancer at autopsy: Understanding tumor biology and racial disparities.”

The study aims to develop smarter screening strategies to accurately identify men at risk for developing advanced prostate cancer while minimizing harms by testing mid-life PSA levels. The study will obtain blood from autopsies of black and white men to assess how PSA in midlife relates to pre-diagnosis natural history of prostate cancer and to determine when racial differences manifest in the natural history of prostate cancer.
