man kind broke through a major bottleneck of cancer treatment: featuring, Oncolytic Virus therapy

basically this cancer treatment works by injecting harmless viruses at the site of a tumor so that the immune system detects cancer but killing the viruses in the cancer and then since the immune system cells are at the cancer site it's extremely easy for the immune system to detect the cancer everywhere sense it now knows what to look for. Remember the immune system is great at killing cancer, just not detecting. That's one of the main bottlenecks of cancer treatment and this therapy literally broke through that bottleneck.
