New research in Nature shows that the immune system can control tumors permanently without destroying cells. The researchers treated cancers with two proteins that activate the immune system (interferon-g and tumor necrosis factor) and found that the combination kept tumors from growing by making the cells dormant. This work could ultimately lead to cancer treatments that are both effective and free of side effects, suggesting that we shift from the "War on Cancer" strategy of killing tumor cells to focus instead on restoring the body’s innate ability to arrest tumor development.
