A Blood Test That Detects Up To 8 Types Of Cancer

New test opens doors for tumors of breast, lung and many others to be detected early through blood

The cancer , even before the first symptoms, begins to leave traces in the blood. They may be small pieces of mutant DNA floating between red and white blood cells, or specific proteins. Each type of tumor – there are far more than a hundred of them – leaves a little different traces. And now we’re on the way to identifying those molecules with a new type of blood test , announced in Science .

When applied to 1005 volunteers with diagnosed cancer, the test identified the disease and organ reached in 70% of the cases – the success rate varied between 39% and 96% according to the type. All with a little bottle of the liquid, no x-ray or magnetic resonance imaging .

Among the types tested are some of the most common: breast , lung, ovary, liver, stomach, pancreas, esophagus and rectum. The method was also tested on 812 people without the disease to check the number of false alarms. There were only seven mistakes.
