If you have been diagnosed with prostate cancer, you are not alone.

During his lifetime, a man has about a 1 in 10 chance of being diagnosed with prostate cancer. Over 200,000 new cases of prostate cancer are diagnosed annually in the U.S.

Prostate cancer is a malignant tumor that begins growing in the prostate gland. It can spread from the prostate to nearby lymph nodes, bones, or other organs. This spread is called metastasis. A male hormone called testosterone can stimulate the growth of hormone-dependent prostate cancer cells.

Prostate cancer is the second leading cause of cancer death in men. But the good news is that survival rates have improved a great deal. In the past 20 years, 5-year survival rates for all stages of prostate cancer combined have increased from 67% to 99%.
