It has been recently revealed in a study that there might be a risk of bone weakening, as the side effects of some of the most commonly used medicines for breast cancer. The study has been recently published in `The Lancet' and has been conducted by researchers from Canada. They are of the view that there is need for giving the patents additional calcium and vitamin D supplements to keep their bones strong, while they are undergoing treatment for cancer.

It tends to take a toll on the mineral density of the bones, and this is why there is need for replacing the same, with the aid of adequate supplements. This has been revealed by Angela Cheung, the lead author of the study from the University of Health Network in Toronto.

"Exemestane is in a class of medications called aromatase inhibitors. It works by decreasing the amount of estrogen production. This can slow or stop the growth of some breast tumors that need estrogen to grow", said Dr. Bhawna Sirohi, head of medical oncology at Artemis Cancer Centre.

It is essential that when a person is undergoing any sort of cancer treatment, the doctors keep a firm check on the calcium levels and give the patient enough supplements for the same, which will help in keeping the person fit to fight the disease better.

This new study and the findings should also be further used towards the research and development of new methods of treating cancer. These methods might include such drugs, that do not seem to harm the calcium levels of the body, or themselves contain calcium in them to help the person be able to fight the disease, while not having to suffer the loss of calcium and decrease the risk of breaking bones.
