Vitamin D and Risk for Breast Cancer According to Hormone-Receptor Status

Vitamin D protected against breast cancer, regardless of ER/PR status.

Evidence suggesting that vitamin D supplementation protects against several malignancies, including breast cancer, continues to accumulate (JW Womens Health Aug 2 2007). In an earlier population-based case-control study, Canadian investigators showed that higher vitamin D exposure during adolescence and young adulthood was associated with less risk for breast cancer later in life. Now, these investigators have assessed whether such protection varies by tumor hormone-receptor status. The association between vitamin D and breast cancer incidence was evaluated according to route of vitamin D acquisition (dietary intake or sun exposure) and tumor receptor status (estrogen receptor–positive/progesterone receptor–positive [ER+/PR+], 450; ER+/PR–,…
