Using PSA to determine prognosis
An interview with renowned radiation oncologist and researcher Anthony D'Amico, M.D., Ph.D.
The 186,000 or so men likely to be diagnosed with prostate cancer in the United States this year will face a myriad of choices and ask countless questions. "Am I going to die of this disease?" is likely the most frequent query. Until relatively recently, this question was nearly impossible to answer. After all, it wasn't until the late 1980s that testing for prostate-specific antigen (PSA) began; before that, most prostate tumors were detected during a digital rectal examination (DRE), when they were advanced enough to be felt through the rectal wall.
