A woman whose jaw bone became necrotic after she received chemotherapy and radiation for tongue cancer is being treated with hyperbaric oxygen therapy at Havasu Regional Medical Center's Wound Care Centre in Havasu City, Ariz. The center uses its hyperbaric oxygen chamber to treat large, slow-healing wounds that arise because of complications from peripheral artery disease, diabetes, radiation and bone infections, and that are not getting enough oxygen to the affected areas.
