Am not questioning your sincerity am just saying there is no evidence to
support the premise that oxygen kills cancer cells. It doesn't and your
post has not presented any information to the contrary.
What does cause many body diseases is low oxygen levels in the blood.
That is caused by such things as mouth breathing and snoring during
sleep.
Low blood oxygen levels from these conditions do in fact contribute to cancer
and several other diseases - yet that's never discussed here on cancer support.
