What Researchers Did
Researchers reviewed existing studies to critically discuss the potential adverse genetic effects of hyperbaric oxygen (HBO) therapy.
What They Found
While no cancer-inducing effect of HBO therapy has been found to date, recent studies indicated that HBO can induce oxidative DNA damage in blood cells of healthy subjects under therapeutic conditions. However, HBO exposure also led to the induction of anti-oxidative defense mechanisms, suggesting that modified treatment regimens could potentially avoid genotoxic effects.
What This Means for Canadian Patients
Canadian patients undergoing hyperbaric oxygen therapy should be aware of the potential for oxidative DNA damage, even though a cancer-inducing effect has not been established. Discussions with healthcare providers about treatment protocols and potential strategies to mitigate genetic risks, such as modified regimens, could be beneficial.
Canadian Relevance
This study has no direct Canadian connection as it is a review of international literature.
Study Limitations
The review highlights observed DNA damage, but the long-term clinical significance and definitive cancer-inducing effects of hyperbaric oxygen therapy remain to be fully elucidated.
