The objective of this study was to determine if vitamin D deficiency is a prevalent problem for female breast cancer survivors (BCS) who have completed treatment for breast cancer. Ninetynine breast cancer survivors and a control population of fifty-five women with no history of breast cancer participated in this study. Serum 25-hydroxy vitamin D concentrations were measured throughout 2007. Dietary and supplement intake of vitamin D was assessed by a food frequency questionnaire. Zip code of residence was used to evaluate potential for skin production of vitamin D. Vitamin D deficiency (<32ng/mL) was observed in 76 of 99 (77%) of BCS, and 51 of 55 (93%) of controls. Women taking vitamin D supplements were less likely to exhibit vitamin D deficiency, but supplementation did not guarantee sufficiency. Vitamin D deficiency appears to be prevalent among both groups. Vitamin D status should be routinely evaluated for all women as part of regular preventive care.
