You want your immune system working properly, not to be suppressed. The immune system is what kills the cancer cells, that we all have in our bodies, before they have a chance to take hold. The question you and your doctor should be asking is "why is my immune system attacking my body?" Your body is adapting to some "poor" condition in the best way it knows know. But asking this question is much more difficult than prescribing a drug, so it isn't often done. Suppressing it is like sweeping dust under the rug.

I invite you to look at John Bergman's videos about the immune system, on youtube. He knows more about the human body than anyone else I have heard. One reason for autoimmune conditions is leaky gut, causing excess proteins to leak into the blood. Another is excess gluten, found in much higher concentrations in modern wheat than what our ancestors would have been exposed to.

The bottom line, eat whole unprocessed plant foods.
