Peer reviewed by two members of Breast Cancer UK independent Science Panel.
Most studies have found low levels of circulating vitamin D are linked to an increased breast cancer risk. The body produces adequate levels of vitamin D if skin is exposed to sufficient sunlight. Other sources include diet or supplements. Studies have not demonstrated that taking vitamin D supplements reduces breast cancer risk, although taking these can restore serum vitamin D levels to a healthy state and are recommended for those unable to achieve sufficiency through sunshine and diet. The main function of vitamin D is maintaining extracellular calcium levels. It may help prevent breast cancer through its actions on cellular differentiation, breast cell growth, programmed cell death, reduction of cancer cell growth and tumour blood vessel formation and its effects on oestrogen pathways.
