They work by stopping the growth of affected cells and helping the immune system to better destroy cancer cells. In oncolytic virus therapy, genetically modified viruses are used to kill cancer cells. The virus is injected into the tumor. It replicates itself, causing the cell to rupture and die. Then there is T cell therapy. In this method, T cells are removed from the blood and changed in the laboratory. They re-enter the body and destroy cancer cells.
