Chemotherapy is a vicious monster that doctors try to control and sic upon the even more horrific disease of cancer. The best case scenario is that a patient goes through the hell of chemo, but the cancer is destroyed.  

Jake Bouma had cancer and after four grueling sessions of chemotherapy, the cancer was gone. He and his wife were told by his oncologist while being taped for Nathan Matta‘s upon coming documentary, Let’s Do This: Facing Hodgkin Lymphoma

It is a powerful scene.
