DMSO for pain? Treating Cancer?

Hi everyone! New here! I have been doing some research on DMSO  and its ability to assist with pain control and "treat cancer." From the research I have done, it seems DMSO has strong support in health benefits relating back to decades, and its benefits are so great - and since it is natural - that no money is to be made from it.

Also there are clinics and cancer orgs that offer/promote the benfits of DMSO therapy.
