Will my doctor check my PSA level during my prostate cancer treatment?

ANSWER

If you are diagnosed with prostate cancer, your doctor will check periodically to see if the cancer is spreading and how well your treatments are working. Prostate-specific antigen (PSA) continues to be the main marker of how the disease is progressing or responding to treatment. Several studies show that PSA doubling time -- the time it takes for a patient's PSA level to double -- predicts how aggressive his prostate cancer is. The faster the PSA level doubles, the more aggressive the cancer.
