BEIJING, Sept. 3 (Xinhuanet) -- People who take a kind of osteoporosis drug named bisphosphonates for more than half a decade may double the risk of getting esophagus cancer, according to Reuters on Friday.

An Oxford study published in the British Medical Journal showed that the researching results are worrying, but doctors should not suggest the patients to immediately change the use of bisphosphonates, which can prevent the bone-weakening of the senior citizens.

Jane Green of Oxford's Cancer Epidemiology Unit said although they were focusing on the worrying results, however, it is only the first such study with long-term follow up that has found such effect.

The researchers analyzed data from the UK GP research database on people over 40 years of age who had various kinds of cancer between 1995 and 2005.

The results showed that people with more prescrptions of bisphosphonates had nearly double the risk of esophageal cancer than people who had none prescriptions.

A previous study using the same database had found no link between bisphosphonates and esophageal cancer, while Green said their study had observed patients for the interval of times as twice as long.
