The Claim
Low-dose computed tomography (LDCT) screening for lung cancer in high-risk adults is associated with an 18.5% probability (95% CI, 5.4%–30.6%) that any detected lung cancer is an overdiagnosed indolent tumor that would not have become clinically apparent without screening, representing a significant potential harm due to unnecessary treatment, anxiety, and healthcare costs.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When doctors use a low-dose CT scan to check high-risk people for lung cancer, about 1 in 5 of the cancers they find might never have caused any problems — meaning those people could be treated for something that didn’t need treating, leading to stress, side effects, and extra costs.

What the research says
1 studyStudy: Overdiagnosis in low-dose computed tomography screening for lung cancer.
This study looked at people at high risk for lung cancer who got low-dose CT scans and found that about 1 in 5 of the cancers found probably wouldn’t have caused any problems if left untreated — meaning they were overdiagnosed and led to unnecessary stress and treatment.
