Machado added: “The effects of the active vitamin D metabolite on the breast are mediated by vitamin D receptors, which controls the expression of genes that regulate cell proliferation, differentiation and apoptosis.

“[Vitamin D] may reduce cancer risk by inhibiting cell proliferation, inducing differentiation and apoptosis, and inhibiting angiogenesis both in the normal and malignant breast.
