'Holy Grail' health test to ID cancer a YEAR before tumours grow

March 28, 2023

More infoA blood test that identifies signs of cancer up to a year before tumours have even formed has been ­developed by scientists. Trial results have proved 100 percent accurate, even detecting cancers in the “control group” of patients who were believed to be cancer-free. The blood biopsy technique, which shows changes in how stem cells are behaving, could be the biggest cancer breakthrough in decades. The trial of 1,000 patients comprised half who had a prior cancer diagnosis or went on to have cancer shortly after follow-up and the other half – the control group – who did not. This includes cell or tissue analysis from biopsies, CT scans, mammograms, X-rays and various blood tests.
