Scientists say a genetically-engineered version of the herpes virus that causes cold sores shows real promise for treating skin cancer.

Research found that when the therapy, called T-VEC, was injected into tumours it could halt their growth, or even eradicate them.

It's the first study to prove an increase in survival using the drug, although it only worked for some melanoma patients.
