If you ask a killers that is are MDs they will spout off garbage such as, bad genes, bad luck, who knows. The source of this disease and many other diseases is simply toxicity and or deficiency. That is to simple for the pompous arrogant big word spouting ignorant killers called MDs as they flood the body with toxins until you die. Fact is MDs may save 3% of the cancer victims and they usually do that by hacking off body parts. They never use the word cure, and use the words like 5 year survival rate. Even the ads from the drug barons never mentions cure but longer survival. It is a sad state of affairs when so called modern medicine ignores these facts of the causes and does the exact opposite of what needs to be done as they call the real healers snake oil salesmen such as the Gerson clinic in Mexico that were run out of the US for successfully curing cancers.
