Non-invasive blood test can detect cancer four years before conventional diagnosis methods

(University of California - San Diego) An international team of researchers has developed a non-invasive blood test that can detect whether an individual has one of five common types of cancers, four years before the condition can be diagnosed with conventional methods. The test detects stomach, esophageal, colorectal, lung and liver cancer. The test detected cancer in 91% of samples from individuals who were asymptomatic when the samples were collected and were only diagnosed with cancer one to four years later.
