A therapy that retrains the body's immune system to fight cancer has provoked excitement after more than 90% of terminally ill patients reportedly went into remission.

Alan Worsley from Cancer Research UK told the programme that this therapy is "another weapon in our arsenal" against cancer.

However, the data has not been published or reviewed and two patients are said to have died from an extreme immune response.
