At the basic level, what are cancer cells?

Dr. Mehmet Oz, MD
Cardiology (Cardiovascular Disease)
Cancer cells are essentially normal cells that have something inside of them that turns them bad (and this originates with mutations). They're kind of like a gang of hooligans who have infiltrated your body. They may start out as good, but something switches inside them so they have total disregard for the rules that govern your body. Of course, your immune system serves as your own police force to bring down these bad cells. But cancer cells can be difficult to catch, because, like thugs who are used to committing and getting away with crimes, are pretty smart about ways to beat the system.
