Heavy smokers should start getting yearly scans for lung cancer and cut their risk of death from the nation’s top cancer killer, this is a long anticipated decision by the U.S. Preventive Services Task Force. Lung cancer kills about 160,000 Americans each year. Smoking is the biggest risk factor, and the more and longer people smoke, the higher their risk.
Usually lung cancer is diagnosed too late for treatment to succeed, since by now there are no good means of early detection. The screening could prevent around 20,000 deaths a year, government advisers said.
