Lipid molecule fuels cancer growth

Cancer cells seldom start off stealthy. Quite to the contrary, they announce their presence to the immune system by planting chemical red flags right on their membranes. Once alerted, the body’s defenses can swoop in, destroying rogue cells before they can do much damage. Lying at the heart of this early warning system are lipids, fatty compounds previously seen by cancer biologists primarily as a fuel source for burgeoning tumors.
