Are there tests that might better show if cancer has come back?

ANSWER

A more accurate way to find out if you have cancer is to test how quickly your PSA levels rise. PSA velocity measures the change in your PSA levels over time. PSA doubling time calculates how long it takes for your PSA level to double. Quickly rising PSA levels could be a sign of cancer. Knowing how fast your PSA is rising can help your doctor predict whether your cancer will spread, and if -- or when -- you'll need treatment.
