There's literally thousands of potential cancer cures. Some professors at my university are using gold nanoshell injections combined with mild radiation therapy (the gold nanoshells attach to cancer cells and amplify the radiation creating a localized high radiation field that only destroys cancer cells, not normal ones), and they have had much better results, and have been in clinical trials for something like seven years. Also, they have gotten support from med schools and hospitals, not companies.
You guys can rage all you want, but all I see is companies doing what they do. Companies can only exist if they make profits, so I don't expect them to do unprofitable things. Hospitals and med schools can get lots of research funding from the government as well as national and international organizations, and it is often times profitable for them to invest in research. This is how the system works. You can't expect a big company to throw their full support behind an untested idea.
