Increased vitamin D intake may help prevent breast cancer by up to 20 percent.
A Harvard Nurses Health Study found a 23 percent lower risk for breast cancer with higher vitamin D levels. The Women’s Health Study found a 35 percent lower risk.
When combining the results of data from the two studies, one researcher found that women with vitamin D levels over 50 were 50 percent less likely to have breast cancer as compared to women with levels below 13.
Among its many benefits, vitamin D has been shown to reduce the risk of obesity, autoimmune diseases, depression and metabolic syndrome, all conditions known to affect women.
Intake of vitamin D has also been linked to lower risk of diabetes, arthritis and cardiovascular disease, according to James A. Dowd, author of “The Vitamin D Cure”.
Dowd walks readers through the process of calculating their individual needs for Vitamin D as measured by their body weight, amount of sun exposure, age and race.
Equally important, another recent study published in Cancer Research, a journal of the American Association for Cancer Research, suggests a possible link between nicotine and breast tumor development and metastases.
The study, conducted by researchers at the Beth Israel Deaconess Medical Center, is among the first to explore the effects of nicotine on mammary cells.
Through a series of in vitro tests Dr. Chang Yan Chen, at Beth Israel Deaconess Medical Center and her team of researchers determined that breast epithelial-like MCF10A cells and cancerous MCF7 cells both express several subunits of nAChR (nicotine receptor), that when bound, initiate a signaling process, potentially increasing cell growth and migration, the press release said.
When injected into the tail of a mouse the cancerous MCF7 cells migrated to the lungs. The study indicates that nicotine is not a conventional carcinogen, but rather it combines with other yet to be determined factors to enable the growth of tumors.
