Genes may shed light on cancer
Times Staff and Wire Reports
Researchers have identified two genetic variations that appear to increase a person’s risk of developing lung cancer by up to 60%, they reported Sunday in the journal Nature Genetics.
Smoking is the leading risk factor, but increasingly scientists are looking to genetics to help explain why some longtime smokers never develop the disease and why some nonsmokers do.
Researchers from 18 countries analyzed genetic mutations in more than 15,000 people -- 6,000 with lung cancer and 9,000 without the disease.
