最近的研究表明，维生素D可能与降低乳腺癌风险有关，但大多数研究只评估了饮食中维生素D的摄入量。2003年至2004年间，在加拿大安大略省进行了一项基于人群的病例对照研究，评估了阳光紫外线辐射、皮肤维生素D产生相关因素和乳腺癌风险之间的关系（n = 3101例，对照3,471例）。在4个生命周期中，户外活动时间与乳腺癌风险降低相关（2010年至2010年vs. 2010年）。
Recent studies suggest that vitamin D may be associated with reduced breast cancer risk, but most studies have evaluated only dietary vitamin D intake. The associations among ultraviolet radiation from sunlight, factors related to cutaneous vitamin D production, and breast cancer risk were evaluated in a population-based case-control study conducted in Ontario, Canada, between 2003 and 2004 (n = 3,101 cases and n 3,471 controls). Time spent outdoors was associated with reduced breast cancer risk during 4 periods of life (>21 vs.
