Researchers are studying changes in PSA levels over time to learn whether the test may someday be useful for early diagnosis of prostate cancer. If a doctor suspects prostate cancer, he or she may recommend a biopsy. This is a simple surgical procedure in which a small piece of prostate tissue is removed with a needle and examined under a microscope.

Doctors have several ways to treat prostate cancer.
The choice depends on many factors, such as whether or not the cancer has spread beyond the prostate, the patient's age and general health, and how the patient feels about the treatment options and their side effects. Some men decide not to have treatment immediately if the cancer is growing slowly and not causing symptoms. Instead, they have regular checkups so they can be closely monitored by their doctor. Men who are older or have another serious illness may choose this option. Surgery usually removes the entire prostate and surrounding tissues.
