Prostate cancer is the most common cancer in men, second only to skin cancer. As men age these can become more common. An annual PSA blood test is recommended for men beginning at age 50. However, men who are at high risk of prostate cancer should start screening at age 40
According to the National Cancer Institute age is the most common risk factor with nearly 63% of prostate cancer cases occurring in men age 65 and older. Other risk factors for prostate cancer include family history and race. Men who have had a brother or father with prostate cancer have a greater chance of developing prostate cancer. No one knows exactly what causes prostate cancer, but early detection and treatment is critical before it has a chance to spread to other parts of the body.
Prostate-specific antigen (PSA) is a protein produced by cells of the prostate gland. The PSA test measures the level of PSA in the blood. Prostate cancer or benign (non-cancerous) conditions can increase men’s PSA levels.
