Summary
Lung cancer kills more people than breast, colon, and cervical cancers combined. Yet it is the cancer we screen for the least. A new study in the Journal of the American Medical Association shows that universal lung cancer screening could change this.
Researchers studied what would happen if lung cancer screening were offered to everyone based on age alone. They found that screening people ages 40 to 85 could prevent 62,000 deaths in the United States over just 5 years. The cost was about $101,000 per life saved. Breast cancer screening costs $890,000 per life saved. Colon cancer screening costs $920,000. That makes universal lung cancer screening both lifesaving and far more affordable.
Why does early detection matter so much? Lungs are large organs with no pain receptors. Symptoms often do not appear until the cancer has spread. More than half of all lung cancers are found at stage IV, when treatment is much harder. But when caught at stage I, survival rates jump to 80% at 10 years, according to the Early Lung Cancer Action Program.
Today, screening is mostly offered to people with a smoking history. But nearly 20% of lung cancer patients have never smoked. Many are younger women. Radon, wildfire smoke, and air pollution may be driving these new cases. Stigma around smoking has slowed progress and left many patients diagnosed too late.
The message is clear. Anyone with lungs can get lung cancer. Universal lung cancer screening based on age would save lives, lower health care costs, and reduce suffering. The science supports it. The next step is action.
