Pope Leo XIV has lung cancer despite never smoking. Lung cancer screening only targets people who did

Pope Leo XIV has been diagnosed with lung cancer, despite having never smoked. Lung cancer screening typically targets individuals with a history of smoking. However, in recent years, the disease has been increasingly diagnosed in never smokers, particularly women. Pope Leo, who is not a smoker, highlights the need for broader screening guidelines that include those without a smoking history.

Early detection of lung cancer, regardless of smoking history, can lead to effective treatment through surgery and sometimes results in a cure. The challenge lies in that individuals who have never smoked often go undiagnosed until tumors are found accidentally. This trend is not isolated to Pope Leo; many younger women and never smokers are being diagnosed with lung cancer.

Researchers attribute this rise in rates to various factors, including genetic predispositions, environmental exposures, and the carcinogenic effects of tobacco smoke. While most lung cancer patients today are smokers, the proportion of never smokers with the disease is growing, particularly among women. Risk factors for lung cancer extend beyond smoking, encompassing family history, exposure to asbestos, radon, and air pollution, as well as potential risks associated with e-cigarette and marijuana smoke.

Women may be at a higher risk due to smoking later in life, the use of filtered cigarettes, and possibly a greater susceptibility to the carcinogenic effects of tobacco. New screening guidelines have expanded eligibility to include younger adults with less smoking history, potentially increasing the number of women undergoing lung cancer screening.

Early detection through low-dose CT scans is crucial for improving outcomes in lung cancer patients.
