Abstract
Vitamin D has been reported as an essential factor for bone health as well as a protective factor for many cancers, with potential effect of the pandemic situation of vitamin D deficiency worldwide. Vitamin D could affect every cell in the human body. Living at higher latitudes and having vitamin D deficiency could result in increasing risk of common fatal cancers. Enough intake of vitamin D could have a beneficial influence on some cancers such as cancers of colon, breast, prostate, pancreatic and ovarian. Both observational and experimental epidemiologic studies have reported that higher intakes of vitamin D are related to lower risk of cancer.
