Blood test spots 8 common cancers based on DNA
US-based researchers have developed a blood test which showed 70% accuracy across eight of the most common cancers when tested in over 1,000 patients. The test is sensitive to mutated DNA in the blood and cancer-related proteins, said researchers. For five cancers with no current screening tests: ovarian, liver, stomach, pancreatic and oesophageal, its sensitivity ranged from 69% to 98%.
