Terminal leukaemia patients have been offered new hope after a new therapy was shown to shrink tumours or make them disappear in 70 per cent of patients.

The new treatment called (CAR) T-cell immunotherapy, extracts immune cells from a cancer patient and modifies them in a lab so they can recognise leukemia cells.

The engineered cells are then infused back into the patient where they multiply and hunt down and kill the cancer cells.
