Lung cancer kills more than 150,000 Americans every year, and when it's diagnosed has a big impact on survival.
This Lung Cancer Awareness Month the American Lung Association has partnered up with the Ad Council to encourage those at particular risk to get screened using a relatively new non-invasive and painless technology.
Their new public service announcement targets former smokers, 55 and older.
The low-dose CT scan detects lung cancer in the early stages, often before there are any symptoms, when the disease is more treatable.
"If everybody who qualified got this scan, it would save about 48,000 lives a year," says the Dana-Farber Cancer Institute's Dr. Jacobb Sands.
Lung cancer is the leading cause of cancer deaths. Less than 20-percent of those diagnosed are alive after five years, but for the 16-percent whose cases are caught early the survival rate improves dramatically.
