Discover how PSMA can help you and your doctor understand your cancer and your options

  • PSMA is one biomarker you can act on. A biomarker is something that can tell your doctor more about your cancer. There are other biomarkers your doctor may look for in prostate cancer

  • It is found on prostate cancer cells, including those that have spread beyond the prostate*

If your cancer has spread beyond the prostate, you are more likely to be PSMA+.

*PSMA can also be found on normal cells.

PSA is something you and your doctor likely have been checking since you were first diagnosed.

  • PSA is found in your blood and measured through a blood test

  • It is another biomarker your doctor looks at to keep an eye on your cancer. A rise in PSA indicates your cancer is getting worse

PSMA is different. It is a biomarker identified through a PET scan. You may have already had a PSMA-PET scan, but cancer changes over time.

If you have advanced cancer and have had multiple treatments, getting another scan can:

  • Identify your current PSMA status

  • Map out if and where the cancer has spread

If a PSMA-PET scan reveals that you are PSMA+, it means that you and your doctor could change the way you manage your disease.
