![]() ![]() The PSA test can find aggressive prostate cancer that needs treatment, but it can also find slow-growing cancer that may never cause symptoms or shorten life. Most men are now offered an MRI scan before a biopsy to help avoid unnecessary tests, but some men may have invasive, and sometimes painful, biopsies for no reason.įurthermore, around 1 in 7 of those with normal PSA levels may have prostate cancer (a false-negative result), so many cases may be missed. PSA tests are unreliable and can suggest prostate cancer when no cancer exists (a false-positive result). Routinely screening all men to check their prostate-specific antigen (PSA) levels is a controversial subject in the international medical community. This is because it has not been proved that the benefits would outweigh the risks. There's currently no screening programme for prostate cancer in the UK.
