Point of view: You’ve recently been diagnosed with breast cancer, and you’re overwhelmed, confused, scared, and more. You are still having a hard time accepting being diagnosed and don’t know where to start in finding out more medical information about your diagnosis as well as trying to prepare yourself emotionally. While you’ve probably received some type of handout from you doctor, there’s still more information that you need to wrap your head about this change in your life. You’ve also likely searched Google for non-medical information but you are having a hard time finding this information.

Traditional cancer therapies (such as chemotherapy and radiation therapy) have shown widespread success against various cancer types, but are known to have toxic, undesirable side effects as they do not selectively kill cancer cells and therefore actively damage healthy cells as well. This is where immunotherapy comes into play. Immunotherapy is a form of therapy that uses the body’s own immune system to fight the cancer within it. Think of your body as a battlefield and your immune system the frontline of soldiers, ready to attack foreign invaders. The problem with cancer cells is that they are not easily recognized as foreign pathogens (such as viruses or bacteria) because they originate in the host’s body and mutate from normal cells. It has long been postulated that the immune system could be used to target and kill cancer cells, but the process of figuring out how to harness this ability is not a simple task.
