Blood test could use DNA to spot early-stage cancers, study shows

DNA and biomarkers could be used to detect and identify cancers, including five types for which there is currently no screening test

Scientists have made a major advance towards developing a blood test for cancer that could identify tumours long before a person becomes aware of symptoms.

The new test, which is sensitive to both mutated DNA that floats freely in the blood and cancer-related proteins, gave a positive result approximately 70% of the time across eight of the most common cancers when tested in more than 1,000 patients.
