The fact that your uncle did not take chemo or medication is probably to his advantage. Chemo does nothing but destroy cells and organs while further compromising an already weakened immune system. Unfortunately, it does not sound like he took any positive alternative steps in fighting his cancer.
I would strongly urge you to take another look at dquixote's post and follow his advice. He has a private forum with over 1,000 members, some of which have come to him in the late stages of cancer and after five years they are still alive with positive results. I believe there have only been a couple of deaths during this time, one being due to the person deciding to follow his oncologist's advice and abandoning alternative measures. I believe the other one was a similar circumstance.
Although Oleander plays a very big part in shrinking to eliminating cancer cells, his entire protocol, or as much of it as possible, should be followed. I will post the link below.
