How to Interpret the PSA Cancer Test

The prostate specific antigen test, or PSA, is a tool used to detect possible prostate cancer in men. The PSA helps detect cancer early before it advances and spreads. There are a few tips for interpreting the results of your PSA that can be used to discuss with your physician whether further testing is needed.

Instructions

• 1

  Ask your doctor what PSA levels would be considered normal for your age and risk level. PSA levels under 4ng/mL are generally considered normal, but the 4ng/mL cutoff varies with age.

• 2

  Notice the first signs of risk. PSA levels between 4ng/mL and 20ng/mL are considered to be fair to moderate risk for having cancer. At this point, your doctor may want to do further testing.

• 3

  Be aware of high-risk PSA levels. PSA levels above 20ng/mL are considered very high risk. Your doctor will want to do further testing to determine if cancer is present and, if so, what type and how advanced.

• 4

  Keep in mind that some medications, such as Proscar, can affect your PSA level. Your doctor should take this into account when evaluating your PSA results.
