Women with ovarian cancer and control subjects were analyzed for their vitamin D status as measured by serum 25(OH)D3 level in 7,243 women from the National Health and Nutrition Examination Surveys (NHANES). A high and low status of levels of serum vitamin D was defined as above or below 23 ng/mL (57.5 nmol/L). After adjusting […]

This prospective study of 512 women with early breast cancer evaluated the role of serum vitamin D levels as a potential factor influencing breast cancer prognosis. The average age was 50 and the average vitamin D levels was 58.1 nmol/L. Vitamin D levels were deficient (<50 nmol/L) in 192 women, insufficient (50 to 72 nmol/L) […]
