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.
In the future, such a test could be used in routine screening programmes to significantly increase the proportion of patients who get treatment early, at a time before cancer would typically show up on conventional scans.
