Researchers from the University of South Carolina (Southern California) that conducted the recent study that found a clear link between low levels of vitamin D and some of the worst and most aggressive forms of breast cancer. Especially in women with dark skin, and found that vitamin A deficiency (d) to be eight times more susceptible to malignant breast cancer from those of women with higher levels.
Of the study, Susan Steak, PhD, MPH, and colleagues from the University of Southern California, assessing 107 women who were diagnosed with breast cancer within the previous five years. The Forty-seven of the women while the other Caucasian, 60 were African American. And provided all the women from the blood samples to researchers who tested the levels of D 25 - hydroxy vitamin (25 Oh d).
The researchers found that women with breast cancer triple negative - I mean, do not contain estrogen, tumors and progesterone, or receptor HER2 - was the blood serum the lowest levels of vitamin D, breast cancer triple negative is now widely recognized as one of the worst and more breast cancer, aggressive, Since it spreads easily and quickly.
In addition to that, he was nearly 60 percent of women of African Americans who
participated in the study, vitamin A deficiency (d), as opposed to nearly 15 percent of women in the Caucasus. Dark skin is not as receptive to UV radiation from the sun - rays that produce vitamin (d) in the skin - and this is why researchers believe that there is a large disparity between the two groups.
"We know that the darker color of the skin to some extent acts as a bloc for the production of vitamin (d) when exposed to sunlight, which is the main source of vitamin (d) In most people," was quoted as saying steak for [Mudbj] today. "We believe that it would be important that [sic] for doctors to monitor blood levels of vitamin (d) of the patients, especially among African-American patients."
When exposed to sunlight are not sufficient, supplementing with vitamin D3 is the next best option. Some doctors recommend taking more than 10000 IU or more per day of vitamin (d) as part of a healthy lifestyle.
