Sadly, there is already a cure for cancer, involving a drastic change in lifestyle(especially diet). It only works in early stages of cancer, but is not considered a "cure" because there are no drugs involved. It involves creating an environment that the cancer cannot live in by altering the body's Ph levels and controlling certain elements(sugars have to be almost eliminated). I know of one person personally who tried it for a form of brain cancer and it worked for them. It was proposed to them by a woman who beat breast cancer. They have been cancer free with no other treatment for over 3 years.
That said, I guess it is nice they found a drug to treat it (since so many people believe that only a pill can cure anything)
