Pre-symptom blood test that detects more than 50 cancers rolled out

This cancer-finding blood test has gotten the green light. 

A blood test capable of detecting more than 50 kinds of cancer — before a person even shows symptoms of the disease — has proven accurate enough to roll out as a screening test for those at higher risk, including asymptomatic patients age 50 or older, according to a press release. “Finding cancer early, when treatment is more likely to be successful, is one of the most significant opportunities we have to reduce the burden of cancer,” said Dr. Eric Klein, author of a paper published Friday that found the blood test boasts a very low false-positive rate and a high level of accuracy for predicting where in the body the cancer is.
