Hypothesis
Does solar ultraviolet-B exposure influence cancer incidence and mortality rates?
Conclusion
The study found that higher solar UV-B exposure is associated with lower cancer incidence and mortality for several cancer types.
Supporting Evidence
- An inverse relationship was observed for ten cancer sites including bladder and prostate.
- Weaker evidence was found for six other cancer sites.
- No association was found for several cancer types including brain and liver cancers.
Takeaway
Getting sunlight can help protect against some types of cancer, especially digestive cancers.
Methodology
The study analyzed cancer incidence and mortality data from over three million cases and deaths, adjusting for various confounders.
Potential Biases
Potential bias due to regional variations in cancer types and misclassification of cancer cases.
Limitations
The study is ecologic and may not account for individual-level variations in sun exposure and other risk factors.
Participant Demographics
The study focused on non-Hispanic whites and included some data on blacks.
