It can be shocking when a person who's never smoked...Gets lung cancer. Now, researchers say, it may be in the genes.
Researchers at Washington University School of Medicine have identified a cluster of genes that appear to significantly increase the risk for lung cancer, regardless of whether a person smokes. They found patients with a specific genetic mutation had a more than five times higher risk for lung cancer.
Researchers hope to one day use this gene to screen patients for the disease.
