Prostate-specific antigen, or PSA, levels fall immediately after radiation treatment, according to the University of California San Francisco Medical Center. However, PSA levels usually take between two and three years to reach their lowest point after radiation.
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.
Typically, the prostate-specific antigen, or PSA levels after radiation therapy drop to very low or even undetectable amounts, states the American Cancer Society. A post-operative check-up of PSA levels is usually recommended within 6 to 8 weeks after surgery.
Free PSA, or prostate-specific antigen, is PSA circulating unbound and by itself within a man's body. Total PSA is the sum of unbound PSA and PSA bound to other substances circulating within a man's body, according to MedicineNet.com.
According to the National Cancer Institute, a normal prostate-specific antigen result is generally considered to be below 4 nanograms per milliliter. Doctors often recommend a prostate biopsy for men with higher PSA levels to determine whether prostate cancer is present.
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
There is no normal or abnormal level of prostate-specific antigen, or PSA, in the blood, according to the National Cancer Institute. Historically, doctors consider levels of 4 nanograms per milliliter of blood to be normal.
A prostate-specific antigen, or PSA, test is intended to measures the level of PSA in the blood. Prostate-specific antigen is a protein that is produced in the prostate gland. This test is carried out by a doctor when trying to diagnose the presence of cancer.
There isn't a prostate-specific antigen level that is considered normal or abnormal, explains the National Cancer Institute. Generally, higher PSA levels increase the likelihood of prostate cancer, or if PSA results rise continuously over time, the risk for cancer also increases.
