title: [Vitamin D and breast cancer].
abstract: The active form of vitamin D, in conjunction with his own receptor, affect a multitude of biological processes in the cell (inter alia it influences the expression of oncogenes and tumor suppressor genes). There is an increasing volume of scientific publications examining the relationships between serum vitamin D levels, vitamin D supplementation and malignant diseases. Some articles suggest inverse relationship between the low serum levels of vitamin D and the breast cancer risk and mortality, whilst other publications do not support this view. Thus the present opinion is conflicted. Vitamin D can exert a beneficial influence on the symptoms and outcomes of a large number of ailments, but its role in affecting cancer is still not completely clear.
