He has been doing alternative therapies for about two years. Dr Z himself will tell you he is here only by the grace of the Almighty because he should have been dead several years ago. The surgery he had was to remove a section of a huge tumor that was pressing on his heart. A prior surgery several years ago left him with only one lung. They had to do the surgery because the tumor was killing him and you are right - it was very risky. The good news is that when doing the surgery to debulk the tumor, they saw that his original cancer was shrinking. If he can pull through this surgery he may actually have some more time with us.
