Prostate cancer is the most common cancer among men in the United States, with an estimated 1 in 8 men being diagnosed with the disease in their lifetime. Early detection and treatment of prostate cancer are crucial for improving the chances of successful outcomes. Several methods are available to check for prostate cancer, including the prostate-specific antigen (PSA) test, digital rectal exam (DRE), and prostate biopsy.
The PSA test measures the level of prostate-specific antigen in the blood. PSA is a protein produced by the prostate gland, and elevated levels of PSA can indicate the presence of prostate cancer. However, it’s important to note that an elevated PSA level does not always mean cancer, as other conditions can also cause PSA levels to rise. The DRE involves a doctor feeling the prostate gland through the rectum to check for any abnormalities. A prostate biopsy is a procedure in which a small sample of tissue is removed from the prostate gland and examined under a microscope to look for cancer cells.
