You may remember the stir that DMSO created in the 1970s when it emerged as a miraculous healing agent and adjuvant for treating many health issues. Some MDs were using it on cancer patients successfully. Then, DMSO mostly faded out of the natural healing picture.
Recently, the Camelot Cancer Care clinic in Tulsa, Oklahoma, featured DMSO as a major part of their protocol, but it was shut down in 2013 by the FDA and FBI after producing a very high healing rate among cancer patients. Apparently, they’ve reopened with the stipulation that they would no longer use laetrile, a natural extract banned in the USA but used effectively elsewhere.
A major aspect of Camelot’s currently allowable orthomolecular (mega-dose vitamin) treatment incorporates DMSO. It has been proven to carry healing compounds deeply and rapidly into tissue while also having its own properties that promote cancer cell apoptosis (cell death). 
Most normal cells are programmed for apoptosis as part of their cycle for allowing new cells to generate. Cancer cells don’t have this property. So they claim immortality by never dying on their own and stick around to form tumors.
DMSO (dimethyl sulfoxide): From industrial solvent to cancer solvent
Medical interest surfaced in the early 1960s at the Oregon Health and Science University Medical School, where Dr. Stanley Jacob discovered that DMSO could penetrate skin and organ membranes without damaging them. Dr. Jacob researched DMSO further and found several topical analgesic applications for animals and humans.
He went further with injecting or ingesting DMSO for a bladder malady, interstitial cystitis (IC). In 1978, the FDA allowed DMSO to be used for IC. Dr. Jacob has consumed a teaspoonful of DMSO daily for over 30 years and has claimed perfect health. 
DMSO has been used to alleviate Crohn’s disease suffering. You can search on YouTube for “DMSO 60 Minutes” videos and witness interesting interviews with Dr. Jacob and some of his patients treated for assorted ailments.
But the big deal with DMSO involves treating cancer. R. Webster Kehr of Cancer Tutorand other sites reported on a series of experiments with cancerous animals which discovered that DMSO targets cancer cells while leaving healthy cells alone. Kehr recommends using DMSO to get high-pH cesium more deeply into tissues contaminated with cancer cells. 
There have been oncologists who have used DMSO with some existing chemotherapy drugs effectively. Instead of the chemo destroying everything in its path as usual, theDMSO escorted the chemo to cancer cells only, thus greatly reducing the amount of chemotherapy needed for a result.
Maybe that’s why doctors who had used FDA/AMA-approved chemo drugs with DMSOwere shut down. Using only 10% of any chemotherapy drug and getting positive results negatively affects Big Pharma and oncologists’ profits.
However, DMSO has been used by itself successfully for cancer. There have been anecdotal cures, and a scientific study published in 2010 in India mentions that much in vitro (lab culture) testing has demonstrated DMSO’s ability to induce apoptosis in cancer
