The aim of this review is to clarify the true role of vitamin D in the onset of breast cancer and evolution of the disease after treatment. These include the role of vitamin D in the induction of apoptosis, stimulation of cell differentiation, anti-inflammatory and antiproliferative effects and inhibition of angiogenesis, invasion and metastasis. There are various mechanisms by which vitamin D influences the natural history of cancer. Recently, extensive research on its extraskeletal actions has linked vitamin D deficiency to an increased risk of infection, diabetes mellitus types 1 and 2, cardiovascular disease, obesity, asthma, inflammatory bowel disease, colon, breast, prostate and ovarian cancer and some neurological diseases.


Vitamin D is a fat soluble vitamin that plays a role in calcium and phosphorus homeostasis.
