One of the main benefits of PSA testing is the early detection of prostate cancer, which can lead to early treatment and improved survival rates. However, there are also risks associated with PSA testing. These include false-positive results, which can lead to unnecessary anxiety and additional testing, and false-negative results, which can give a false sense of security. Overdiagnosis and overtreatment are also concerns, as some prostate cancers detected through PSA testing may never cause symptoms or become life-threatening.
