Has he been tested for lymphoma?..............I don't want to scare you..........but I do believe in getting earliest possible treatment............but "medical" treatment can't start until there is a dx.............enlarged lymph nodes,fever, weight loss and diarrhea( I believe) are some of the symptoms..............also while your waiting for further tests...........research the family tree..........you'd be amazed the "secrets" and long forgotten dx's............may point you in the right direction...................still believe, with a major boost to immune system will help him recover..............you've probably heard of these................but do you know what they are designed to do?
Coenzyme Q10..........improves cellular oxygenation
DMG...............a personal favourite.........enhances oxygen utilization
Garlic..............increases immune function
Beta carotene.............helps cells repair and rebuild
The omegas..............repair and produce new cells
I do believe in medical science...............however there's alot we can do for ourselves............that complements the medicine>GL<
