Castration-Resistant Prostate Cancer

Over time, prostate cancer cells can find new ways to grow or spread. This can happen even if you are receiving treatment to help lower your testosterone levels. Prostate cancer that continues to progress despite low levels of testosterone is known as castration-resistant prostate cancer (CRPC).

Prostate cells, including cancerous ones, produce something called prostate-specific antigen, or PSA. When prostate cancer cells start to multiply despite treatment, your PSA levels may rise. That’s why your doctor may monitor your PSA levels over time.

Being Prepared for Prostate Cancer Progression, Bill

How will I know if my prostate cancer is castration-resistant?
PSA tests may help determine if your cancer is progressing. If your test results show elevated PSA levels despite low levels of testosterone, this may be a sign that your cancer is castration-resistant.

If your PSA test results continue to rise over time, talk with your doctor about what this could mean. It’s important to remember that a single PSA test is not enough to determine if your cancer is progressing. That’s why your doctor may recommend additional tests.
