A lung cancer screening using computed tomography (CT) may detect malignancies beyond the lungs, a recent analysis suggests. The findings, published in JAMA Network Open on April 13, 2026, indicate that screenings designed to identify lung cancer in current and former smokers can also incidentally reveal other types of tumors.
Researchers conducted a retrospective analysis of a U.S. Cohort to evaluate the potential for identifying extrapulmonary malignancies—cancers originating outside the lungs—during lung cancer screenings. The study focused on individuals with a history of significant tobacco leverage.
The research highlights the importance of considering incidental findings during lung cancer screenings. While the primary goal of these screenings is to detect bronchial carcinomas, the analysis suggests they can also lead to the discovery of other cancerous growths in the body.
The detection of these incidental findings could have implications for early diagnosis and treatment of various cancers, potentially improving patient outcomes. This is particularly relevant as lung cancer screening programs become more widespread.
The study’s publication comes as lung cancer screening programs are being implemented more broadly, underscoring the need to understand the full scope of potential benefits and considerations associated with these screenings.
