More than 1 million people now have completed an online quiz to determine if they are eligible for lung cancer screening, according to the American Lung Association (ALA).
As of April, 1,051,303 people have completed the quiz as part of the association's Saved by the Scan campaign. The ALA partnered with the Ad Council in 2017 to start the campaign.
The organization also highlighted surveys it conducted that show that the campaign led to an increase in doctor visits for lung cancer screening for people who smoke. In 2017, about 26% of people who used to smoke talked to their doctor about the scan and 18% got scanned, according to the association. In 2022, about 35% of people who used to smoke had talked to their doctor about lung cancer screening and 28% had gotten scanned, the ALA noted.

Top row: Images in a 68-year-old male patient with higher 10-year mean ambient air pollution exposure (7.9 μg/m3 for particulate matter measuring ≤2.5 μm in diameter [PM2.5] and 17.4 parts per billion [ppb] for NO2) with extensive CAD (coronary artery calcium score [CACS] >1,000 and obstructive CAD [≥70% diameter stenosis]). Bottom row: Images in a 57-year-old female patient with lower 10-year mean ambient air pollution exposure (6.3 μg/m3 for PM2.5 and 4.6 ppb for NO2) with no CAD (CACS = 0 and no obstructive stenosis).](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2026/06/hanneman.r6SMLzkezo.png?auto=format%2Ccompress&dpr=2&fit=crop&h=167&q=70&w=250)
