The human body uses three main nutrient-sensing pathways, insulin, mTOR, and AMPK, which also act as growth factors. When the body senses more available nutrients (high insulin, mTOR, and low AMPK), conditions favor growth, which favors cancer cells. The lung cancer is now not just surviving, but also finding good soil to grow. But it’s getting a little too big and unwieldy—time to leave home.
