Vitamin E and selenium reduce breast cancer risk

Effect of deficiencies of selenium and vitamin E alone or in combination on the induction of mammary carcinogenesis by 1-methyl-1-nitrosourea

This study evaluated the role of vitamin E and selenium in the prevention and/or treatment of breast cancer. Mice were assigned to different groups that were either deficient or adequate in selenium and/or vitamin E. After 30 weeks it was found that animals fed the adequate amount of selenium and vitamin E had a lower risk of developing cancer. The study results also suggested that a deficiency in selenium and vitamin E can promote tumor growth. Further details can be found in the study.
