About Prostate Cancer
Prostate cancer is one of the most common types of cancer found in men: One in six will get it during his lifetime. The American Cancer Society estimates that 192,800 new cases of prostate cancer were diagnosed in 2009 in American men. For unknown reasons, it occurs more frequently in African Americans.
Some prostate cancers grow slowly and stay confined to the prostate gland, where the cancer may live for a long time without causing serious health problems. It may need little or no treatment. Other types of prostate cancer behave with opposite characteristics, being aggressive and spreading quickly.
Prostate cells secrete the protein PSA or prostate specific antigen. High PSA levels in the blood can indicate the presence of prostate cancer and are used to screen for the disease.
