Cancer is hard for lots of reasons, but the main reason we have not made the progress we should have is the way we are going about looking for new treatments. Our animal models don't reflect natural human disease, we use the wrong way of classifying cancers (by tissue of origin rather than sensitivity), and we require that all new treatment provide a rapid response in terminal patients (stage I/II trials). If you made me cancer dictator with an NIH sized budget and an ability to set the rules I could provide very rapid progress.
Edit. I normally don't care about being down voted, but on a serious topic like this it really does everyone a disservice. If you disagree with something I have written then please reply rather than mindless reaching for the down arrow.
