First of all, all disease is diet related and comes from within. Louis Pasteur admited on his death bed that he was wrong..."the microbe is nothing, the terrain is everything".
The terrein is defined as your body's PH balance and related oxygen environnment.
Eat only organic, and eat what God intended us to eat:

Genesis 1:29(ESV) And God said, “Behold, I have given you every plant yielding seed that is on the face of all the earth, and every tree with seed in its fruit. You shall have them for food.

"Let thy food be thy medicine, and thy medicine be thy food" - Hippocrates

Doctors are great for emergencies, cuts, broken bones, and repairs, but they fall very short when it comes to disease. Alopathic medicines is a failure, and against the will of God. Pharmaceuticals are rarely the answer.

Seek naturopathic, holistic medicine...
