Despite aggressive treatment and screening efforts, breast cancer remains the second leading cause of cancer-related deaths among women in the United States (1). Because of the large number of women dying from this disease and the toxicity of breast cancer treatments, recent efforts have focused on identifying effective cancer preventive agents. These efforts have led to the development of antiestrogen agents, such as tamoxifen and raloxifene, which prevent approximately 50% of invasive breast cancers in women who are at high risk for breast cancer. However, the use of these agents for breast cancer prevention has been limited by their toxicity.
A large amount of evidence exists to indicate that vitamin D may be a particularly promising cancer preventive agent. Vitamin D is a fat-soluble vitamin that is essential for bone formation and calcium homeostasis. The potential link between vitamin D levels and reduced cancer incidence was suggested by
