British scientists have developed a pioneering blood test to boost survival chances by quickly identifying breast cancer types so patients can quickly be put on the best treatment

A new blood test has been developed which could “transform” how the NHS monitors and treats breast cancer.

The test can identify what type of cancer without the need for a full biopsy meaning patients can quickly be put on the treatment most likely to work. Currently an invasive biopsy is generally needed to cut out a piece of the tumour, which takes longer to analyse.

In one in five patients the type of breast cancer also changes during treatment, which can cause the treatment to stop working or be less effective. A trial of 86 breast cancer patients by the Institute of Cancer Research in London showed
