Bisphosponate Drugs

According to a study by U.S. researchers drugs used to prevent and treat osteoporosis and similar diseases could lower the risk of breast cancer by almost 40 percent.

The study involved 6000 women between 20 and 69 of age which were interviewed about their bone health, whether they’d been diagnosed with osteoporosis and their history of bisphosponate use.  For testing purposes half had been diagnosed with invasive cancer and half not.

The study found that women who were not obese and used bisphosponate drugs for more than two year had a nearly 40% reduction risk in compared to those who did not. “This large study provides new evidence that the use of bisphosphonates is associated with a potentially important reduction in breast cancer risk”, said lead author Polly Newcomb, head of the Cancer Prevention Program at Fred Hutchinson Cancer Research Center.

More research is needed because the way in which bisphosponate drugs may prevent breast cancer is unknown. “These drugs may affect cell function and be important in cell growth and death – specifically the death of tumors or even premalignant disease”, said Polly Newcomb.
