Atlanta, Georgia — A recent study highlights that significantly more lung cancer deaths could be averted if screening rates for American adults were increased to full eligibility levels. Current statistics reveal that only about 20% of eligible individuals underwent lung cancer screening in the past year, representing a stark missed opportunity for improving outcomes in a disease that accounts for the highest cancer mortality in the U.S.
The findings, published in the Journal of the American Medical Association, indicate that increasing lung cancer screening from the current 19% to 100% could prevent nearly 30,000 deaths annually and result in over 482,000 additional years of life. Lead researcher Priti Bandi, who oversees cancer risk factors and screening research at the American Cancer Society, described the low screening rates as disappointing and underscored the critical need for change.
Lung cancer remains a pressing public health issue, contributing to approximately 125,000 deaths in 2025 and frequently diagnosed in 225,000 new cases each year. Eligibility for low-dose CT scans—an effective screening method—generally includes adults aged 50 to 80 who either currently smoke or have quit within the past 15 years and have a significant smoking history defined as at least 20 pack-years.
Despite the clear guidelines, research indicates that around 13 million Americans qualify for these screenings, yet only a fraction has taken advantage of them. Bandi emphasized the importance of communication between patients and their healthcare providers, urging those in the at-risk age range who have a smoking history to discuss screening options with their doctors.
Additionally, advocates stress that expanding eligibility criteria could play a pivotal role in saving lives, such as allowing access for former smokers regardless of how long it has been since they quit. Lisa Lacasse, president of the American Cancer Society Cancer Action Network, noted the vital role of policymakers in facilitating access to preventive care and ensuring that screening procedures are fully covered by insurance.
The implications of these findings are significant, suggesting that fostering a culture of preventive healthcare can greatly impact lung cancer mortality rates. Bandi and Lacasse both called for heightened awareness and advocacy to drive down lung cancer deaths and improve health outcomes for many Americans.
Individuals who smoke or have previously smoked and fall into the age bracket should consider consulting their healthcare providers about eligibility for screening. Enhanced efforts to raise awareness and ease access to necessary screenings could ultimately work toward reducing the alarming statistics surrounding lung cancer mortality.
