Doctors move towards universal blood test to detect cancer


Scientists have taken a step towards a universal blood test for cancer.              
A team at Johns Hopkins University has trialled a method that detects eight common forms of the disease. 

The Cancer Seek test looks for mutations in 16 genes that regularly arise in cancer and eight proteins that are often released. 

It was trialled on around one thousand patients with cancers that had not yet spread to other tissues. 

Overall, the test found 70 percent of the cancers.
