Haha, those "alternative healing method" people make me laugh. They tout its benefits for something like the sniffles and then they're first people flying to the doctor's office for chemo.
You really think it's possible to cure all cancers? You have no idea how the human body works.
Actually....there is no money in cures. Think about it. Find a drug to beat heart disease. How many heart surgeons, hospitals, surgical tools specific to heart surgery, medications after surgery, etc would be pissed if that happened?
