AACR LogoBreast cancer is said to refer to cancers deriving from breast tissue, most commonly from the inner lining of milk ducts or the lobules that provide the ducts with milk. A study claims that vitamins and calcium supplements seem to decrease the possibility of breast cancer.

The experts believe that the discoveries propose that the calcium supplements are presumably acting to improve DNA repair capacity. It is a complicated biological procedure concerning over 200 proteins that, if interrupted, could result in cancer.

“It is not an immediate effect. You don’t take a vitamin today and your breast cancer risk is reduced tomorrow. However, we did see a long-term effect in terms of breast cancer reduction,” commented, Jaime Matta, Ph.D., professor in the Ponce School of Medicine in Puerto Rico.

The study author added, “This process involves at least five separate pathways and is critical for maintaining genomic stability. When the DNA is not repaired, it leads to mutation that leads to cancer.”

The study incorporated roughly 268 women with breast cancer and around 457 healthy controls. Women were said to have more chances of contracting breast cancer if they were older, had a family history of breast cancer, encompassed no past record of breastfeeding and seemed to have lesser DNA repair capacity.

Vitamin supplements presumably decrease the threat of breast cancer by roughly 30 percent. Calcium supplements decreased the danger of breast cancer by around 40 percent. After controlling for the level of DNA repair capacity, calcium supplements were said to be no longer as defensive, but the connection between vitamin supplements and breast cancer drop supposedly stayed.

The study was presented at the American Association for Cancer Research 101st Annual Meeting 2010.
