To the question "Is there a cure for cancer?", the answer according to most people would be something like "Not yet, but research is getting closer to finding a cure every day" or "We hope to finally have a cure available to end cancer within the next five, ten or maybe twenty years..."
This is also what I used to believe... Until very recently. I found out that there isn't one cure out there for cancer, but in fact there are many cures already available today.
