Lung cancer screening holds significant promise for early detection, which can be crucial for improving survival rates. However, there is a substantial gap in participation, as just 18% of those recommended for screening in the United States actually take part. Despite the assumption that individuals at risk may be resistant to seeking preventive healthcare, a recent study published in JAMA challenges this notion, providing new insights from researchers at Mass General Brigham.
The research team conducted a thorough examination to understand the engagement of those eligible for lung cancer screening with other preventive healthcare services. Utilizing data from the 2022 U.S. Centers for Disease Control and Prevention Behavioral Risk Factor Surveillance System, they analyzed responses from 28,483 individuals aged between 50 and 79 who met the criteria for lung cancer screening. The findings revealed a stark contrast: while only 17-18% of eligible participants underwent lung cancer screening, a significantly larger 65% accessed screenings for breast and colorectal cancers—a rate approaching four times higher.
Alexandra Potter, a researcher in the Division of Thoracic Surgery at MGH and the study’s first author, commented on the implications of these findings. “Our research indicates that many individuals eligible for lung cancer screenings are indeed receptive to receiving preventive care services. This suggests that the low participation rates in lung cancer screenings do not stem from a reluctance to engage in healthcare, but rather from a range of other factors that may inhibit screening uptake,” she explained. According to Potter, the complexities inherent in lung cancer screening eligibility—requiring consideration of both age and detailed smoking history—contrast with the simpler age-based criteria for breast and colorectal cancer screenings. Additionally, logistical challenges related to accessing screening clinics are likely contributing to the phenomenon.
The conclusions drawn from this study point towards a population that is already proactive about preventive care but highlights a critical need for enhanced outreach and support. The research advocates for initiatives aimed at improving awareness regarding lung cancer screenings and addressing the significant obstacles that hinder high-risk individuals from participating.
Dr. Chi-Fu Jeffrey Yang, the senior author and a member of the Division of Thoracic Surgery at Massachusetts General Hospital, emphasized the collective responsibility in tackling this issue. “As a community, we must unite efforts to bolster awareness of lung cancer screening and work to eliminate the barriers that currently impede high-risk individuals from obtaining these vital screenings,” he urged.
