10 percent of lung cancer patients never smoked

According to Dr. Nasser Hanna, an associate professor of hematology/oncology at the Indiana University School of Medicine and a physician-researcher with the I.U. Melvin and Bren Simon Cancer Center, 10 percent of lung cancer patients are non-smokers.

"Exposure to second-hand smoke and such long-term occupational risks as working in factories and coal mines put non-smokers at increased risk."
