Assessing your prostate cancer

Assessing Your Prostate Cancer Icon

There are multiple ways your doctor will assess your prostate cancer. A PSA (prostate-specific antigen) test is often used after diagnosis to help monitor your cancer response or progression. Although a PSA test can be helpful, it will not provide you and your doctor with a complete picture of your cancer. Aside from a PSA test, other tests—such as a computed tomography (CT) scan, a magnetic resonance imaging (MRI) scan, or bone scans—and physical exams can help your doctor assess your cancer.

Because a single PSA test will not give you a complete picture of your cancer, it’s important to talk with your doctor about other tests that can be used to monitor your prostate cancer.
