PSA levels tend to decrease after radiation treatment, reports the American Cancer Society. However, the drop in a PSA level is gradual and can take up to 2 years or more for the level to reach its lowest point. PSA refers to the prostate-specific antigen, which is a protein produced by the prostate

A rise in PSA levels after radiation can mean that the prostate cancer has returned, explains the American Cancer Society. In some cases, a person's PSA levels may have an occasional rise, which is only cause for regular monitoring.

The prostate-specific antigen, or PSA, test measures the level of the prostate-specific antigen present in a man's bloodstream; PSA is a protein made by the prostate gland. Elevated PSA blood levels may indicate prostate cancer, though other conditions also cause high PSA levels, according to the Na
