You need professional help, especially if time is of the essence.
I would recommend you see Dr. Arnold Takemoto in Phoenix arizona, he does a very high dose of IV Vit.C [ not gm corn derived] as well as other immune boosting substance, coffee enemas [would not be recommended as he has bowel problems] strict diet and viral/bacteria/ parasites treatment. He's expensive, but what is the cost of a human life.
Also Dr, Bihari in New York, treats cancer/HIV/autoimmune diseases with Low Dose Naltrexone with a great deal of success.
You have to get on top of this quickly. No time for messing around!
FASTING is not a good thing for people with cancer, as it weakens the body. Cancer weakens your body, and that is what people usually die from. You have to build up your body, improve your immune system, lessen the viral/ parasite loads, and provide the right environment for healing to take place.
I can provide you with contact details, and lots more info if you wantit.
Good luck, and dont stop, there is a way.
