Breast Cancer may be Caused by Vitamin D Deficiency

October 19, 2004

Women who do not utilize vitamin D well enough will often get breast cancer and fibrocystic breasts are a sign of calcium and vitamin D deficiency.

Much suggests that vitamin D prevents breast cancer. If so, sunlight, which is the overall dominant source of vitamin D, can significantly prevent breast cancer.

The theory is now supported by a new English study that has shown that women who utilize vitamin D badly have doubled the risk of getting breast cancer.
