Editor in Chief Marc B. Garnick, M.D., explains why spotting blood in semen probably isn't cause for alarm
Several weeks ago, an anxious colleague came into my office and closed the door. "I think I might have prostate cancer," he said quietly. After a moment of stunned silence, I asked him about his prostate-specific antigen (PSA) level and whether he had had a biopsy. "I haven't had a PSA test recently, and I've never had a biopsy," he replied. "What makes you think that you might have prostate cancer?" I asked. "Well," he said, "my wife and I had sex last night, and she noticed that there was blood in my semen."
