I can't say I'm very impressed by that theory. I think other theories account for viruses, muscle loss, etc in a more comprehensive way.
For example, nagalese is produced by viruses and cancer cells. Nagalese damages our ability to make GcMAF, an immune system stimulant. GcMAF essentially tells our macrophages--Pacman-like white blood cells--to fight the threat to survival.
Dr Nick Gonzalez explains the theory of Dr James Beard about the role of stem cells and pancreatic enzymes in the development and fight against cancer. This theory has its roots in Beard's work 100 years ago and has had notable success. Gonzalez's long time medical partner continues his work in NYC.
The explanation of cancer by Dr Jerry Tennant is the best I've seen. He accounts for the successes and failures of so many other treatments and theories better than anyone I've come across. I consider him to be an extension of the Beard-Kelly-Gonzalez tradition. https://www.curezone.org/forums/fm.asp?i=2425292#i
