UCSD.edu - Using newly available data on worldwide cancer incidence, researchers have shown a clear association between deficiency in exposure to sunlight - specifically ultraviolet B (UVB), which causes vitamin D3 production in the skin - and breast cancer. ucsd.edu -使用新的数据对全世界的癌症发病率，研究表明，一个清晰的协会之间的不足，在接触到阳光-特别是紫外线B（中波紫外线），从而导致维生素D3生产的皮肤-和乳腺癌。

UVB exposure triggers photosynthesis of vitamin D3 in the body.紫外线曝光引发光合作用的维生素D3在体内的。 This form of vitamin D also is available through diet and supplements.这种形式的维生素D也可通过饮食和补充。

Approximately 1,150,000 cases and 410,000 deaths from breast cancer occur annually worldwide, including 215,000 new cases and 41,000 deaths in the United States.大约一百十五点零万箱子和41.0万人死于乳腺癌的发生，每年全球的企业，包括21.5万新的情况和4.1万人死亡，在美国。

The study is published in the May-June 2008 issue of The Breast Journal .这项研究是发表在五月2008年6月的问题， 乳腺杂志 。

“This is the first study, to our knowledge, to show that higher serum levels of vitamin D are associated with reduced incidence rates of breast cancer worldwide,” said Cedric F. Garland, Dr. PH, professor of Family and Preventive Medicine in the UCSD School of Medicine, and member of the Moores UCSD Cancer Center. “这是首次研究，我们的知识，显示较高水平的维生素D相关的减少发病率的乳腺癌在全世界，说： ” cedric楼加兰博士， pH值，教授，家庭和预防医学，在加州大学圣地亚哥分校医学院的，和会员的moores加州大学圣地亚哥分校癌症中心。

This paper used worldwide data only recently available through a new tool called GLOBOCAN, developed by the World Health Organization’s International Agency for Research on Cancer.本文全世界使用的数据是最近才可以通过一个新的工具，所谓的globocan ，发达国家由世界卫生组织的国际癌症研究机构。 GLOBOCAN is a database of cancer incidence, mortality and prevalence for 175 countries. globocan是一个数据库的癌症发病率，死亡率和患病率为175个国家。

The researchers created a graph with a vertical axis for breast cancer incidence rates, and a horizontal axis for latitude.研究者建立了一个图形与垂直轴为乳腺癌的发病率，和横轴为纬度。 The latitudes range from -50 for the southern hemisphere, to zero for the equator, to +70 for the northern hemisphere.纬度范围从-50为南半球，以零为赤道，以70为北半球。 They then plotted age-standardized incidence rates for 175 countries according to latitude.然后，他们策划的年龄标准化发病率为175个国家根据纬度。 The resulting chart was a parabolic curve that looks like a smile.由此产生的图表是一个抛物线曲线看起来像微笑。

“In general, breast cancer incidence was highest at the highest latitudes in both hemispheres,” said Garland. “一般来说，乳腺癌的发病率是最高的在最高纬度地区在这两个半球，说： ”花环。 “Even after controlling for known variables such as meat, vegetable and alcohol intake, cigarette consumption, weight, fertility and others, the inverse association of modeled vitamin D status with breast cancer incidence remained strong.” “即使在控制了已知的变量，如肉类，蔬菜和酒精的摄入量，卷烟消费，体重，生育等，逆协会仿照维生素D的地位，与乳腺癌的发病率仍然强劲” 。

In the paper, the authors caution that this was a study of aggregates, or countries, rather than individuals; findings that apply to aggregates may not apply to individuals.在文件中，作者提醒大家，这是一个学习的总量，或国家，而非个人;结果，即适用于总量可能并不适用于个人。 They recommend further research to study individuals for the effect of vitamin D from sunlight, diet and supplements on the risk of breast cancer.他们建议进一步研究，以研究个人的影响维生素D的阳光，饮食和补充，对患乳腺癌的风险。

This is the fourth environmental paper from this research team to show a strong association between vitamin D and cancer using global incidence data (GLOBOCAN).这是第四次环境的文件从这个研究小组，以显示强大的协会之间的维生素D和癌症使用全球发病率的数据（ globocan ） 。 The first paper, which illuminated a similar pattern for vitamin D and kidney cancer, was published Sept. 15, 2006, in the International Journal of Cancer .第一份文件，这会发亮的类似的模式，为维生素D和肾脏癌，出版了2006年9月15日，在国际癌症期刊的 。 The second, on ovarian cancer, was published Oct. 31, 2006, in the American Journal of Preventive Medicine .第二，对卵巢癌，出版了2006年10月31日，在美国杂志预防医学 。 The third, on endometrial cancer, was published Sept. 16, 2007, in Preventive Medicine .第三，对子宫内膜癌，出版了2007年9月16日，在预防医学 。
