Hypothesis about nature of cancer

Cancer cells are like recycle bins for molecules that are recognized as being foreign or toxic by the body. Changing focus from fighting cancer to the source of toxins might give a clue to cure cancer naturally. Accessive glucose in the blood stream might be the culprit. High glucose level is toxic for the body and at the same time cause high insulin level. Insulin forces cells to grow. Cancer cells as being recycle bins have no any resistance mechanism against insulin action and starts to grow exponentially. There is why diabetics usually die from a cancer not diabetes.
