Albeit the doctors are careful in calling the patient cured, by using a third-party's immune cells, genetically modified to seek out and destroy the cancer while working in a foreign body, a one-year-old girl appears to have completely recovered from leukaemia.

The basic idea is to remove immune cells from a patient’s body, genetically engineer them to attack cancerous cells and place them back in the body. Several human trials are already underway around world. Some trials involve adding a gene for a receptor called CAR19, which sits on the outside of the T-cells. This programs the T-cells to seek out and kill any cells with a protein called CD19 on their surface – which is found on the cells that cause acute lymphoblastic leukaemia.
