Hypothesis
Overdiagnosis may explain the results reported by Bucchi et al.
Conclusion
The author argues that there is evidence supporting an inverse association between tumor size and overdiagnosis.
Supporting Evidence
- There are many recent papers discussing the link between mammography screening and overdiagnosis of small tumors.
- Joensuu et al. reported a high level of length time bias in screening detected cancers.
Takeaway
The author thinks that finding small tumors through screening might lead to overdiagnosis, which could explain some research results.
