Tracking cancer with a blood test

Blood tests that fish for either tumour DNA or cancer cells in patient blood samples are showing great promise. This type of blood analysis is helping Cancer Research UK scientists and doctors better understand the biology of cancer from its earliest origins to when it spreads around the body. And it has the potential to offer a new way of monitoring how patients respond to treatment, as well as how drug resistant tumours may begin to emerge.
