The Claim
Among lung cancers detected by low-dose computed tomography (LDCT) screening, bronchioloalveolar carcinoma (now classified as minimally invasive adenocarcinoma) has a 78.9% probability (95% CI, 62.2%–93.5%) of being overdiagnosed, indicating that nearly 8 in 10 of these tumors are likely indolent and would not progress to cause symptoms or death without screening.
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 lung cancer is found through a special low-dose CT scan, almost 8 out of 10 of a certain type of tumor might be harmless and would never hurt the person if left alone—only the scan found it, and it wouldn’t have caused any problems otherwise.

What the research says
1 studyStudy: Overdiagnosis in low-dose computed tomography screening for lung cancer.
This study looked at lung scans used to find cancer early and found that almost 8 out of 10 of a certain slow-growing type of lung tumor found this way would never have hurt the person if they hadn’t been scanned. So the claim is right.
