The biggest difference between a healthy cell and a cancer cell comes down to how they make energy. Healthy cells thrive on oxygen. When oxygen and glucose are used together, the body produces 38 molecules of ATP—the fuel that powers life. Cancer cells, however, are damaged. They can’t use oxygen to make energy, so they rely on a much less efficient process. This metabolic weakness is one of cancer’s greatest vulnerabilities—and it’s why therapies that restore oxygen and cellular health are so p
