London's Institute of Cancer Research scientists develop a more accurate saliva-based DNA test for early prostate cancer detection.

Scientists at The Institute of Cancer Research in London have developed a spit test, which is more accurate than existing blood tests, for early detection of prostate cancer. The DNA test, extracted from saliva, identifies men at risk of aggressive cancers, sparing those at lower risk from unnecessary treatments. If further research confirms the test's effectiveness, it may be introduced to screen men with symptoms or a higher risk due to age or ethnicity, potentially saving thousands of lives each year.
