For people with a history of heavy smoking, detection of significant incidental findings (SIFs) on low-dose computed tomography (LDCT) screening scans was associated with a 13.89 per 1000 marginal risk difference for extrapulmonary cancer in contrast to those with no SIFs, according to a study involving over 26,000 people.
