NEW YORK, Nov 29, 2004 (United Press International via COMTEX) -- The risk for lung cancer, the top U.S. cancer killer, can now be predicted for social smokers as well as habitual smokers.

Dr. Claudia Henschke, of New York-Presbyterian Hospital/Weill Cornell Medical Center in New York City, presented the findings at the annual meeting of the Radiological Society of North America. They showed that a social smoker age 50 or older has a risk for developing lung cancer similar to that of a smoker under age 50 who smoked three packs a day for 20 years.

With annual CT screening, which identifies a high percentage of Stage I lung cancer -- the most curable form of lung cancer, there is a 76 percent to 78 percent chance of a smoker's lung cancer being cured, Henschke said. However, delaying treatment by more than six months resulted in increased tumor disease and often a higher stage of the disease.

Regardless of a smoker's age or how much has been smoked, the risk for developing lung cancer does not decline appreciably until 20 years after quitting, according to Henschke.
