I am skeptical of cancer. For one thing, I wonder what is killing people; Cancer or the Cancer treatments??? No question that surgeries medications, chemotherapies and tests of all sorts are bombarding the body as a whole and not just the "cancer" part. So I wish that when someone is said to have "died from colon cancer" they would just come right out and say they "died while being treated for colon cancer." Moreover they should name the organ that failed...e.g. the liver. Many people who are treated for cancers die not specifically from the cancer but from failure of the liver or heart or lungs due to the treatments themselves.
The language here is vital. Dying of cancer is one thing, dying while being treated for cancer is a totally different one.
Anyone who is taking harsh and dangerous medications "for treatment" cannot be said to die of cancer.
