How new blood test could reveal cancer long before symptoms appear

Scientists at Johns Hopkins University in the US have developed a new blood test that can detect signs of cancer up to three years before symptoms appear. When cancer is present, tumours release small fragments of genetic material into the bloodstream. Researchers found that these fragments can be identified in blood samples long before symptoms emerge. This could allow doctors to detect cancer much earlier than current screening methods, improving the chances of timely treatment
