What type of screening should follow a PSA test for men over 50?

Following a PSA test for men over 50, a digital rectal exam (DRE) is recommended as a complementary screening method for prostate issues, including prostate cancer. The PSA test measures the level of prostate-specific antigen in the blood, which can indicate the presence of prostate problems. However, the PSA test alone does not provide a complete picture, as false positives can occur and elevated levels do not definitively indicate cancer.

A DRE involves a healthcare provider physically examining the prostate gland through the rectal wall. This approach enables the clinician to detect abnormalities in the prostate's size or texture that may not be evident from blood tests alone. The combination of both tests enhances the accuracy of screening for prostate cancer, allowing for earlier detection and more strategic treatment options when necessary.

Other options, while useful for different health assessments, do not specifically follow a PSA test in the context of prostate screening. A chest X-ray is primarily utilized for conditions related to the lungs or chest cavity. A colonoscopy is aimed at screening for colorectal cancer, and a blood glucose test assesses diabetes risk. Thus, these options are not directly connected to follow-up care for prostate cancer screening.
