From the common cold to complex viruses, our immune system is incredible at fighting off infections. So why not use our own immune system to fight cancer?

Cancer is not only smart, but it adapts to different circumstances. So much so, that – on its own – our immune system is not able to identify cancer cells as foreign. These cells are different from normal cells, in that they do not die normally. These abnormal cells frequently change, or “mutate,” to evade the immune system, so the cancer is left alone and multiplies.

However, immunotherapy drugs are designed to alert the immune system about these mutated cancer cells so it can locate and destroy them.

So, what cancer types does immunotherapy treat? And why does immunotherapy work for some but not others?
