American Lung Cancer Screening Initiative
Lung cancer screening can find disease earlier, when treatment has the best chance to work. We bring that opportunity closer to the people who need it.
More people screened. More lives saved.

When to ask about lung cancer screening
A low-dose CT scan can look for lung cancer before symptoms appear. Your age, smoking history, and overall health help determine whether annual screening makes sense.
Take the eligibility surveyA healthcare professional can help weigh the benefits and possible harms of screening. These details are from the U.S. Preventive Services Task Force recommendation. The American Cancer Society guideline does not use years since quitting as a cutoff.

Plus One starts with a question
How Plus One works
ALCSI volunteers ask whether someone knows a person aged 50 to 80 with a smoking history who may benefit from learning about screening. The conversation can connect a friend or family member with information they did not have before.
