A blood test that can detect cancer before any symptoms are noticeable is being hailed a breakthrough that could save thousands of lives.
The test, made public at the British Science Festival, has been compared to a smoke detector by the researches that discovered it.
“The test can be likened to a ‘cancer smoke detector’ because a smoke detector does not detect the presence of fire in our homes but its byproduct — smoke,” Professor Gareth Jenkins, who led the study at the Swansea University Medical School, said.
