New technology could detect cancers earlier

A simple blood test being developed by genomics company Illumina could spot cancer signs from drops of blood in healthy people before any signs of symptoms. Renowned tech founders like Bill Gates and Jeff Bezos have backed Grail with joint funding of $100m. Grail, a company set up by gene sequencer IIIumina, have been set the task of developing the new technology. The “liquid biopsy”, would work by detecting fragments of DNA which are signatures for cancer within the blood as it develops.
