What if we could get a vaccine that would prevent us from getting cancer, by causing our immune systems to protect us from it–just like a flu shot does. This may be on the way.
Our immune systems have trouble recognizing cancer cells as dangerous, so it does not act to destroy them. But we may be able to manipulate our body’s defenses so they will attack cancer cells.
On the Life Extension website, Henry A. Davis quotes immunologist Kunle Odunsi as saying, "There is a slew of data indicating that an immune response can lead to better outcomes in cancer. The question is, how can we harness this power of the immune system?"
