Don't take the hydrogen peroxide orally use a nebulizer. Try 3 ml to start start with and then adjust by diluting with water if it seems too strong or work your way up to a higher ml if you can tolerate it well. Continue six 6 times daily for six months then be reevaluated. After a year the nodule on my lung had not progressed.
I did the same thing at the same time using 3 ml of baking soda mixed with 3 ml 20 mule team borax (never use boric acid) in 1 quart water. The excess in the quart can be used to make graviola or green tea. So far, for me, it stopped the lung cancer.
I feel fine except I'm 83 yrs old and that'll slow some folks down.
Good luck, David
