Health clinics worldwide are using hyperbaric oxygen to supplement cancer therapy. Recent studies have shown that HBOT in combination with the ketogenic diet increases mean survival time in mice models by up to 75%. This works by starving cancer cells of their main energy source, glucose, and introducing a high oxygen environment. When combined with current conventional treatments, results have been very promising. HBOT is also effective post radiation to prevent bone loss and small vessel damage. Prevention and a healthy lifestyle of consistent exercise, good nutrition, sleep, community involvement and HBOT contributes to improved health outcomes.
