Lung Cancer Screening Among Mammography Patients: Knowledge, Eligibility, Participation, and Interest

Area of Science:

• Pulmonology
• Radiology
• Public Health

Background:

• Lung cancer screening eligibility criteria were updated in 2021.
• Women undergoing screening mammography represent a population with existing engagement in cancer screening.

Purpose of the Study:

• To assess lung cancer screening eligibility, knowledge, and interest among women undergoing mammography.
• To evaluate the impact of the expanded 2021 lung cancer screening criteria.

Main Methods:

• A survey was administered to women at two academic medical centers.
• Eligibility for lung cancer screening was determined using 2013 and 2021 USPSTF guidelines.
• Data were analyzed using descriptive statistics and comparative tests.

Main Results:

• 33% of surveyed women had a history of smoking.
• The 2021 criteria increased eligibility from 7% to 11% among women with a smoking history.
• Eligible women showed high interest (73%) but low awareness (42%) and prior screening (28%).

Conclusions:

• Expanded lung cancer screening criteria identify more eligible women among mammography patients.
• High interest in lung cancer screening exists, but awareness and participation are low.
• Integrating lung cancer screening with mammography appointments could enhance participation.
