Vitamin D Reduces Risk Of Breast Cancer

Vitamin D Reduces Risk of Breast Cancer

Vitamin D from dietary intake and sunlight exposure early in life is associated with lower risks for hormone receptor-positive breast cancers and hormone receptor-negative tumors, according to findings published in the October 15th issue of the American Journal of Epidemiology. Intake of vitamin D during adolescence and early adulthood was most consistently associated with a significantly reduced risk of ER+/PR+ tumors. An association was found between ever having taken cod liver oil at ages 10 to 19 years and a significantly reduced risk of breast cancer.

Similar to the dietary findings, the team found that greater sun exposure earlier in life was more consistently associated with a reduced risk of breast cancer.
