A blood test which can detect traces of cancer cells could spare thousands of patients unnecessary chemotherapy every year.A major bowel cancer trial is examining whether the test can show if surgery has removed all of the tumour.Doctors say half of patients with stage 3 bowel cancer are cured by surgery alone so by using chemotherapy they are over-treating many people.
