My weak, frail grandmother, I think age 77 has squamous lung cancer. There will be no surgery or chemotherapy but they want to do radiation. She has pneumonia caused by this cancer and is on oxygen and all that. A lot of antibiotics and does breathing treatments. She can go off the oxygen for an amount of time but if it was something that would take a long time would need the oxygen again, has a home and portable ones now. I want to cure her and have been reading a lot about 35% food grade hydrogen peroxide. Does anyone have any experience with anything I have stated in this thread? Please help. I need to know in simple terms how to start the H2O2 therapy.
