Does a PSA level of 28.9 mean prostate cancer? Doctors explain

A PSA reading of 28.9 ng/mL is very high but does not by itself confirm prostate cancer, doctors told The Indian Express. Prostate-specific antigen is a marker of prostate abnormality rather than a cancer-specific test, and levels can rise with age and several other conditions. A very high value makes cancer more concerning and calls for further tests.
