In 1924, Otto Warburg noticed something strange about cancer cells. They consume enormous amounts of glucose but don't use oxygen to break it down efficiently the way healthy cells do. They burn sugar fast, extract very little energy from each molecule, and dump the leftover as lactate. It looks wasteful. It looks counterproductive. And yet every aggressive cancer does it. Why? This paper proposes that the Warburg effect is not reprogramming. It is damage. Specific, cumulative, structural damage to the machinery that extracts energy from sugar. Tumor blood flow is unstable, so oxygen cuts in and out for years. Each time it returns, it causes a burst of damage, the same kind that happens in a heart attack, but happening continuously. The damage hits the energy machinery and the DNA that builds it. Each round makes the next round worse. Eventually the efficient path stops working and the cell falls back to the wasteful one because it's all that's left. This makes a clear prediction. One of the four parts of the energy chain (Complex II) is built differently and should stay intact while the others are damaged. Advanced tumors should show this exact pattern. It also flips the treatment logic. If the engine is broken, you don't starve the cancer. You feed it. Force more fuel through the broken machinery than it can handle. Healthy cells process the extra fine. Cancer cells choke on it. The paper describes a protocol built on that idea, using cheap, repurposed drugs. No patients have been treated. This is a hypothesis worth testing, not a treatment.
