Last updated: January 2025

Summary

PSA testing can help find prostate cancer early, when it’s easier to treat.

Not everyone with a high PSA level will have prostate cancer and not everyone who is found to have a cancer will need treatment.

Talk to your family doctor about the risks and benefits of the test to see if it’s the right choice for you.
