Will try to research for you later and write again. My heart goes out to you. You will have to make a decision on the chemo as it is your life. I would be dead wrong to tell you something which could lead to your demise.
For me I will never take chemo because I know it is a death sentence. I have tons of relatives who went that route, but maybe in your case it was necessary. This is between you and your doctor.
Why are you sick, because they are radiating you to death. Doctors do not want you to go the natural route because it is not money for them in their pocket. Money and hospitals well that is another case.
Take care of yourself, please pray to God for guidance.
