Why So Many People Still Are Not Screened for Lung Cancer
The Pope's case is strange in the best way: a man in his 80s, presumably never a smoker, whose lung cancer was found early enough to matter. That's exactly the group the current screening criteria ignore. You have to be 50 to 80, carry a 20 pack-year smoking history, and still be smoking or have quit within the last 15 years. Non-smokers and people who quit decades ago are simply invisible to the system.
I think the real issue is that we're stuck with a blunt instrument. Pack-years and age brackets are crude proxies for actual risk, and they were built from clinical trials that mostly enrolled older, heavier smokers. We have better tools now, genetic markers, AI that can read a chest X-ray for subtle patterns, but the guidelines haven't caught up. The weird part is that a single low-dose scan is cheap and low-risk, yet we ration it based on averages rather than individual biology.
I'd want to know how many lung cancers in non-smokers are diagnosed at late stages each year just because nobody looked. The data exists, but it doesn't fit neatly into the trials that built the current rules. Maybe the next step is to widen eligibility. We also need to ask why we treat a simple scan like a luxury when the cost of missing it is measured in years of life.
