Genetically engineered virus could be a life line


A new type of cancer therapy that uses a common virus to infect and destroy harmful cells is showing big promise in early human trials, say UK scientists.

One patient's cancer vanished, while others saw their tumors shrink.

According to the BBC , the drug is a weakened form of the cold sore virus - herpes simplex - that has been modified to kill tumors.

"Larger and longer studies will be needed, but experts say the injection might ultimately offer a lifeline to more people with advanced cancers".
