Radiation therapy doesn’t just kill off cancer cells, it also ignites the immune system. When the tumor dies off or is affected by radiation, that breakup process allows more exposure of remaining cancer cells to the immune cells. Immunotherapy uses the body’s own immune system to fight cancer. The therapy keeps immune cells alive longer so they can do an even better job of attacking cancer cells. We’re now learning that the timing of when we give treatments, especially immunotherapy, is much more important than we previously thought. We now tailor the timing of immunotherapy and radiation to the type of cancer a patient has and the other treatments they’re receiving. This allows us to get the best results.
