DEAR DOCTOR K: I recently had a PSA test and my levels came back elevated. I'm scheduled to have a prostate biopsy. What can I expect?
DEAR READER: The prostate-specific antigen (PSA) blood test is a screening test designed to detect prostate cancer before symptoms develop. An elevated PSA value can suggest that cancer may be present. But only a prostate biopsy can confirm the actual presence of cancer.
