Scientists have discovered when a cancer-killing virus is injected in the bloodstream it hitches a ride on blood cells and evades attack from the immune system, allowing it to reach cancer tumors, and start destroying cancer cells. They suggest this means it may be possible to use promising "viral therapy" during routine outpatient sessions, like chemotherapy, to treat a wide range ofcancers.
Certain viruses, like the reovirus, that causes colds and mild stomach upsets, prefer to attack cancer cells. They also stimulate the immune system to attack tumors.
