All cancers are genetic in origin. When genes are working properly, cell growth is tightly regulated, as if a stoplight told cells to divide only so many times and no more. A cancer occurs when something causes a mutation in the genes that limit cell growth or that repair DNA damage.



This is true even if the carcinogen is environmental, like tobacco smoke or radon, or if the cause is viral, like Helicobacter pylori or human papillomavirus.
