Low Vitamin D May Mean Worse Breast Cancer
http://abcnews.go.com/Health/OnCallPlusBreastCancerNews...

Vitamin D deficiencies have long been associated with disease, but new research suggests that low levels of vitamin D in women with breast cancer can lead to more aggressive forms of the disease, and even death.

New research suggests low vitamin D levels may be tied to more agressive forms of breast cancer.Researchers at the University of Toronto studied the correlation between vitamin D levels in the blood, the rate of breast cancer metastases -- the incidence of having the cancer spread -- and the overall survival rates of 512 women who were diagnosed with breast cancer between 1989 and 1995. The women were followed until 2006.

Researchers found for the first time that women who were vitamin D deficient at the time of their breast cancer diagnosis were 94 percent more likely to have their cancer spread, and 73 percent more likely to die from their cancer, compared with women who were not vitamin D deficient.

Moreover, researchers found that about 75 percent of the women had a vitamin D deficiency at the time of their diagnosis.

1. Vitamin D's effectiveness is dependent upon stimulation by a modicum of exposure to sunlight.

...But while its effect on bones may be its most commonly known property, vitamin D also has many other subtle but very important functions. For example, it reduces the risk of diabetes and certain forms of cancer including ovary, breast, colon and prostate; it has been shown to improve hypertension; help psoriasis; and it drastically reduces the risk of heart disease. There are even some studies that link Alzheimer's disease, depression and multiple sclerosis to low vitamin D levels.

...vitamin D. Once believed to do little more than regulate bone health, vitamin D is a multi-functional hormone precursor that is increasingly being recognized as a crucial factor in protecting against various cancers, preserving bone integrity, bolstering the immune system, and even warding off debilitating depression.1-3

...In a breakthrough report, the effects of administering 1,000 IU a day of vitamin D (with calcium) was evaluated in 1,180 postmenopausal women living in the Midwest.10

After four years, the risk of contracting any cancer was 60% lower in the vitamin D (and calcium) group, compared with the placebo arm of the study.
