The Claim
The overdiagnosis rate for non-small cell lung cancer (excluding bronchioloalveolar carcinoma) detected by low-dose computed tomography (LDCT) screening is estimated at 22.5% (95% confidence interval, 9.7%–34.3%), indicating that over one in five of these cancers may be indolent and therefore do not require treatment.
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 special low-dose CT scan to find lung cancer early, about 1 in 5 of the cancers they find might never cause harm — meaning the person would never have known about them if not for the scan, and they wouldn’t need treatment.

What the research says
1 studyStudy: Overdiagnosis in low-dose computed tomography screening for lung cancer.
This study looked at people screened for lung cancer using a special CT scan and found that about 1 in 5 of the cancers found might not be dangerous and wouldn’t need treatment — just like the claim says.
