Breakthrough discovery made in cancer treatment

Supplemental oxygenation could shrink tumors and improve cancer immunotherapy, researchers have discovered. "The anti-tumor effects of supplemental oxygen can be further improved by the natural antagonist of the A2A adenosine receptor, which happens to be the caffeine in your coffee," the lead researcher said. "People drink coffee because caffeine prevents the A2A adenosine receptor in the brain from putting us to sleep."
