Doubt over prostate cancer test
Experts have cast doubt on the value of a widely used test for prostate cancer. US researchers found the prostate specific antigen (PSA) test did not improve survival rates.
The researchers found men screened using the PSA test died from the disease at about the same rate as those who were not checked.
The study, which looked at 1,000 men, led by Yale School of Medicine, appears in the journal Archives of Internal Medicine.
Prostate cancer is the most common form of the disease among men in the UK, with more than 27,000 new cases, and 10,000 deaths each year.
The test works by measuring levels of a protein – prostate specific antigen – in the blood.
Levels are often raised in people with prostate cancer.
