So diving NITROX causes cancer? Hmm. Geez, don't tell PADI. There is a large hyperbaric medicine department here at the hospital. I'll be glad to see if I can find someone to talk to me about this if it seems worthwhile. (I'm just a computer hack) Surgery patients, particularly surgeries in which scarring is especially undesirable commonly use O2 chamber time to heal quicker. Since this is done so often, perhaps the time needed to affect the DNA is longer than a person can stand high ppO2 without convulsing? -Steve email: Steve.Breland@rm*.ed*
