Researchers at the M.D. Anderson Cancer Center in Houston believe they have uncovered a genetic variation that may predispose some people towards cigarette addiction and make them more susceptible to developing lung cancer—as much as 80% higher than those without the variation. This finding may in the future allow for the development of screening tests and various treatments to aid those smokers in ending their addiction.
According to Christopher Amos, of the authors of the study, the gene is “kind of a double whammy … It also makes you more likely to be dependent on smoking and less likely to quit smoking.”
The study, being published in the journals Nature and Nature Genetics, may also help to explain why some people can smoke for a lifetime and not develop lung cancer
