Short answer

Several possible studies

No clear answer.

More than one paper fits the article's details, and none fits well enough to single out. Checking claims against the wrong study would be worse than not checking them at all.

Checked against the study summary. The full text wasn't available, so some details couldn't be settled either way.

What the story asserts. With no source study, there is nothing to check these against.

Claim 1 of 6Not checkedPope Leo will undergo surgery in the coming days to remove a lung nodule that was detected during a routine checkup.View evidenceHide evidence

Not checked

NewsLink could not identify one source study, so this claim was not compared against a paper.

Claim 2 of 6Not checkedLung nodules are small growths in the lungs, usually detected on chest imaging, and many are picked up incidentally on scans done for unrelated reasons.View evidenceHide evidence

Not checked

NewsLink could not identify one source study, so this claim was not compared against a paper.

Claim 3 of 6Not checkedLung nodules are very common, including in people without a smoking history; the article cites a study finding nodules in 37.7% of women and 47.5% of men in a CT-screened nonsmoking cohort, and says 31% of chest CT scans in the United States detect nodules.View evidenceHide evidence

As stated37.7%, 47.5%, 31%

NewsLink could not identify one source study, so this claim was not compared against a paper.

Claim 4 of 6Not checkedMost lung nodules are harmless, with the article stating that around 95% are benign, while a small fraction, about 3.7% to 5.5%, may be early lung cancer.View evidenceHide evidence

As statedaround 95%; 3.7%–5.5%

Not checked

NewsLink could not identify one source study, so this claim was not compared against a paper.

Claim 5 of 6Not checkedClinicians judge whether a nodule is likely benign or cancerous by considering features such as size, density, location, prior imaging changes, age, smoking status, and family history; the article says biopsy, machine-learning tools, and biomarkers may help with this decision.View evidenceHide evidence

Not checked

NewsLink could not identify one source study, so this claim was not compared against a paper.

Claim 6 of 6Not checkedIf a nodule is confirmed to be cancerous after removal, follow-up treatment may be recommended, and the article cites one study of early-stage non-small cell lung cancer reporting recurrence risk of 6% to 10% for the first four years after surgery, then 2% per year afterward, with new lung cancer risk remaining 3% to 6% over time.View evidenceHide evidence

As stated6%–10% for four years; 2% per year; 3%–6%

NewsLink could not identify one source study, so this claim was not compared against a paper.
