I once read an Ebay auction where a guy was selling the transcript of his conversation with God where God answered all the questions of life and death including the cause and cure for cancer. Shit was $10,000, but he said the cause of cancer was consuming our own DNA....just throwing that out there
He also said God said that when we die we turn into stars, so, you know, take that with a grain of salt.
Cancer is caused by synergistic chemicals in our world. When combined they create non soluble toxins that force cellular mutations. Cures exist. They create the disease so they can sell us a treatment until we die.
