Dr. Otis Brawley is the chief medical officer of the American Cancer Society and he recommends an annual screening for lung cancer with low-dose computed tomography (CT) in adults ages 55 to 80 who are at high risk for lung cancer because they have smoked a pack or more per day of cigarettes for at least 30 years and currently smoke or have quit within the past 15 years.
Low-dose CT is an imaging technology involving low doses of radiation.
This is important news, as 160,000 Americans die of lung cancer every year.
It is estimated that this test could eventually prevent between 8,000 and 22,000 lung cancer deaths per year.
About 85% of lung cancers are due to cigarette smoking; 37% of Americans are current or former smokers and 20% still smoke.
