Scientists in Israel say that they have developed a blood test that can detect cancers before any symptoms have begun. The test has successfully identified colorectal cancer and can also be used to screen for pancreatic cancer, the scientists say.
The blood test will now enter clinical trials testing for pancreatic cancer, a cancer which is normally found once people have symptoms or through routine screening. Scientists say that they can adapt the test for a range of other cancers too.
In a peer-reviewed study, the blood test was accurate in 92% of cases.
