Scientists Develop Blood Test That Can Detect Cancer Four Years Before Symptoms
To arrive at the findings, the researchers analysed samples of 605 people — who previously had no symptoms of cancer — collected between 2007 and 2014. A team of researchers in China have discovered a blood test that can detect cancer up to four years before symptoms appear, in a latest study. The study, published in Nature Communications, a scientific journal, on Tuesday, revealed that the test — christened PanSeer — could detect cancer in 95% of individuals who had no symptoms before but diagnosed with the disease later. The researchers found that it could also test cancer in the different parts of the body including stomach, gullet, bowel, lungs and liver before conventional diagnosis is administered. To arrive at the findings, the researchers analysed samples of 605 people — who previously had no symptoms of cancer — collected between 2007 and 2014. Out of the selected samples, 191 were later diagnosed with cancer. The researchers also examined specimens from an additional 223...
