Hello-
I am so sorry to hear about your 59 year old with lungcancer. Please go to http://www.H2o2-4u.com and read EVERYTHING you can on that website. Also please go to http://www.stopcancer.com and read everything you can there as well.
There are many people who have been able to get rid of their cancer with a diet that has mostly green vegetables (no meat and no Sugar and a small amount of carbohydrates). When they use FOOD GRADE HYDROGEN PEROXIDE it makes a BIG DEAL in being able to get rid of the cancer. ALso there is a book called Flood Your Body with Oxygen that talks about how if you drink Food Grade Hydrogen Peroxide, you can help control the cancer if you eat mostly green vegetables. There are many people who brought Food Grade Hydrogen Peroxide and they take 25 drops of it 2 times a day along with the diet and it has made a big difference. Please read as much as you can about it and I am really really wishing you luck. Take care and I hope this information can help you.
