Another major organization has joined the U.S. National Cancer Institute to support CT lung cancer screening as a life saving procedure! Recently, the American Lung Association updated its recommendations to support low-dose CT lung screening for smokers and former smokers.
Lung cancer continues to be the leading cause of death in the U.S., with more than 150,000 deaths annually and a five year survival rate as low as 15 percent. However, research from the US National Cancer Institute’s Lung Cancer Screening Trial gives promising hope. The study found that low-dose CT can reduce mortality rates by at least 20 percent among smokers and former smokers. Other published reports have estimated even higher rates of mortality gains! According to the LCST, individuals between the ages of 55 and 74 years who are current or former smokers of at least 30 pack-years and have no history of lung cancer are ideal candidates for lung cancer screening with CT.
Currently, besides never smoking, low-dose CT screening is the only viable option for significantly reducing the risk of lung cancer. The ALA’s recommendation of this medical imaging exam is an important step toward the development of widespread population-based CT screening program through the U.S.
The ALA joins the National Comprehensive Cancer Network, the first major professional organization to recommend low-dose lung cancer screening last fall.
