'Trojan horse' cancer-fighting injection sparks hope in human trials

Promising method simulates a viral infection to mobilise the body's immune system against tumours

German researchers on Wednesday presented a "Trojan horse" method of attacking cancer, sneaking virus impersonators into the human body which prompt an immune response that attacks tumours.

Tested in only three people so far, the treatment claims to be the latest advance in immunotherapy, which aims to rouse the body's own immune system against disease.
