Their findings are reported in the October 1 issue of Cancer Research, a journal of the American Association for Cancer Research.

According to the researchers, about 70 percent of patients who develop breast cancer have advanced secondary tumors in the bone. The spread of cancer to the bones leads to cellular processes that exist physically break the bone, leading to further pain and disease. In fact, the breakdown of bone and the bones of what new forms of higher growth author Colin R. Dunstan, Ph.D., terms a "vicious circle" that transforms the bones in an environment conducive to the growth of cancer.

To better understand the role of bone turnover in the spread of cancer, Dunstan and his team compared the effects of low and the supply of calcium in mice. They found that calcium deficiency food-independent chemical factors that control the turnover is associated with an increase significantly higher in the cancer cell proliferation and the total proportion of the bone, which had been penetrated .

"These results may have implications for patients with breast cancer and bone metastases, which are at high risk of developing metastatic disease," said Dunstan. "A lot of older women in our community are known to be deficient in calcium due to low dietary calcium or due to a deficiency of vitamin D. These women may be at increased risk for the devastating effects of bone metastases. "

According Dunstan, his call for more results of clinical trials conducted" to investigate how the calcium and vitamin D status to influence the progression of metastatic disease, and to determine if corrections of calcium and vitamin D are important for patients of breast cancer. "
