Oct 19, 2022 · The authors found a significant dose-response correlation between UV exposure and breast cancer risk such that women in the highest exposure groups had a 30% lower risk of breast cancer compared to women in the lowest exposure groups (OR=0.70, p<0.001).

May 22, 2023 · The authors found the strongest breast cancer risk reduction among the women with the highest amount of sun exposure and vitamin D intake during the ages of 10 to 19 years old, with a weaker association at 20 to 29 years old and no association for the oldest group.

May 15, 2024 · A significant dose-response correlation between UV exposure and breast cancer risk was found, such that women in the highest exposure groups had a 30% lower risk of breast cancer compared to women in the lowest exposure groups. Overall, this study saw a negative correlation between UV exposure and breast cancer risk, especially among women over ...

May 19, 2022 · For women, UVB was significantly inversely correlated to bladder, breast, colon and rectal cancer. Pedersen et al. found that long-term occupational UV exposure was associated with a reduced risk of late-onset breast cancer among Danish women, with longer durations and higher amounts of UV exposure contributing to a further decreased risk.

May 23, 2022 · The authors found the strongest breast cancer risk reduction among the women with the highest amount of sun exposure and vitamin D intake during the ages of 10 to 19 years old, with a weaker association at 20 to 29 years old and no association for the oldest group.

In the present assessment, we found an overall negative association between exposure to solar ultraviolet radiation and breast cancer risk, perhaps because sunlight (at 280–315 nm) catalyzes the synthesis of vitamin D, which can reduce breast cancer risk.

A new meta-analysis suggests that getting at least 1 hour of sun exposure per day in summer may decrease the risk of breast cancer. But it’s not clear whether sun exposure itself or some related factor, such as physical activity, is responsible for the potential benefit.

Nov 19, 2013 · Among those with the T/T genotype at rs2239181, usual sun exposure ≥ 1 hr/day was associated with a 30% decrease in the odds of breast cancer (OR = 0.7; 95% CI: 0.4, 1.1) relative to usual sun exposure < 1 hr/day.

Conclusions: We found lower risk of breast cancer associated with greater sun exposure in a population living with high, continuous sun exposure. This beneficial finding should be placed in the context of other effects of sun exposure.

To our knowledge, this was the first meta-analysis to estimate the risk of developing breast cancer associated with time spent in the sun. The results suggest that obtaining greater than an hour a day in the sun during the summer months could decrease the risk of developing breast cancer. https://doi.org/10.1289/EHP4861
