We know smoking contributes to lung cancer, but why do some smokers, heavy and light, get the disease and others don’t?
The results from a recent study by researcher Jian-Min Yuan brings us closer to an answer. “We’ve known for a long time that smoking increases a person’s risk for getting lung cancer, but we have not been able to clearly answer why one smoker would eventually develop lung cancer and another one would not,” says Yuan, SPH associate professor and Masonic Cancer Center researcher. “Now we know one definitive link.”
