This is a great link for Lung Cancer alternative treatments. There is a lot of reading but if you go to the end it does discuss vaporizing with foodgrade H202. Apparently one must be careful in treating the lung cancer because as the cancer is attacked it can produce mucus, inflammation, and congestion. It does discuss treatment options and suggests things like DSMO and MSM (as well as other things) to fight the inflamation. A lot of information available here. Paula
