Can we teach our body to recognize cancer?

Mar 02, 2017 https://c1.staticflickr.com/6/5519/11857240186_a24d969536_b.jpg

By Christina Marvin Immunotherapy is an entirely new way of thinking about cancer treatment. Traditional therapies such as surgery, chemotherapy, and radiation aim to target and destroy tumors. Often times, tumor targeting is poor or the treatments damage other parts of the body. Immunotherapy, on the other hand, teaches our body’s natural defenses (the immune […]
