Our test also includes testing your Prostate Specific Antigen (PSA) level. Whilst research indicates that it is unlikely that TRT increases the risk of prostate cancer, caution is advised - particularly if you already have prostate cancer. The PSA marker can help to detect prostate cancer earlier. However, it has several shortcomings when used as a screening test. Besides being increased by prostate cancer, urinary tract infection, recent ejaculation, and even some forms of exercise can also raise PSA.
Currently, the most reliable way of determining whether someone has a true positive or false positive is by performing a prostate biopsy. Because the PSA test has a high false positive rate, many of these prostate biopsies will have been unnecessary.
