Lung cancer screening rates rise nationwide, including in Minnesota

A new national report published in JAMA Internal Medicine found that lung cancer screening participation increased between 2022 and 2024, with encouraging gains seen across many populations and states. Among racial and ethnic groups, American Indian and Alaska Native individuals saw the largest increase in up-to-date screening rates nationally.  The report also identified significant gains in Minnesota, reflecting broader momentum around efforts to improve awareness, access, and early detection through lung cancer screening.  Despite the progress, researchers note that the screening rates remain low overall, underscoring the continued need for outreach and access to care.

Lung cancer screening can help detect cancer earlier, when treatment options may be more effective and outcomes may improve. Current U.S. Preventive Services Task Force guidelines recommend annual low-dose CT screening for certain adults at high risk for lung cancer, including individuals with a significant smoking history.

Despite recent gains, the report found that only one in four eligible adults nationwide were up to date on screening in 2024. Researchers also noted that progress has not been equal across all populations, highlighting the continued need for outreach, education, and access to care.  Barriers such as limited awareness, transportation challenges, cost concerns, and access to screening programs can still prevent eligible individuals from being screened.

Researchers and clinicians at the Masonic Cancer Center, University of Minnesota say findings reflect the importance of sustained community partnerships and continued efforts to improve access to screening.  Abbie Begnaud, MD, who leads the University of Minnesota Health Lung Screening Program, has worked alongside collaborators focused on increasing awareness, reducing barriers to care, and building trust around screening in communities that have historically faced disparities in access and outcomes.

“This progress is encouraging and highlights what is possible when outreach, education, and community collaboration remain a priority,” said Begnaud. “There is still more work ahead to ensure eligible individuals are aware of screening and able to access it.”

The findings offer encouraging signs that lung cancer screening efforts may be reaching more people across Minnesota and beyond. At the same time, researchers say continued investment in outreach, navigation, and access to care will remain critical to improving screening participation and reducing disparities in lung cancer outcomes.
