London, June 1 (ANI): British scientists have developed a simple blood test that can detect a cancer before a tumour has taken shape.
Described as offering a "paradigm shift" in cancer diagnosis, the test - due to be introduced in Britain by early next year - is the first to identify accurately the signals sent out by a person's immune system as a cancer germinates.
According to the research, such signals can be detected up to five years before a tumour is spotted, priming doctors to intervene at the earliest moment when a solid cancer appears, reports The Times.
Brainchild of scientists at the University of Nottingham though a spin-out company called Oncimmune, the technology works by identifying how the immune system responds to the first molecular signs of cancer development.
Professor John Robertson, a breast cancer specialist who led the research, said: "The earliest cancer we have seen is a cancer that has been screen detected, and yet biologically that's late in the road of cancer development.
"We are starting to understand carcinogenesis in a way that we have never seen before - seeing which proteins are going wrong, and how the immune system responds."It's as if your body is shouting 'I've got cancer' way before a tumour can be detected." (ANI)
