Screening is hard: Prostate cancer screening is actually difficult, currently we don't have a really good test that reliably tells us if a man has prostate cancer.The PSA (prostate specific antigen) test used for cancer can go up and down and not always be due to prostate cancer. When we do prostate checks by digital rectal exam that can cause the PSA to go up. Many men have prostate enlargement and not cancer.
