Hip Implants Don't Increase Chance of Cancer


WebMD Health News

Sept. 18, 2001 -- Implants used for hip joint replacement surgery are known to contain some substances that have the potential to cause cancer. And as more hip surgeries are done, some experts have been concerned about the effects this could have on the health of those living with hip implants.

Some of the chemicals in the implants themselves are known to have the potential to cause cancer, and some small medical studies have even suggested that they could be causing cancer in humans.

So researchers from the International Epidemiology Institute in Rockville, Md., looked at a group of almost 120,000 people who received a hip implant over a 30-year period and found that these people had no more chance of getting cancer overall then the rest of the population.

However, they did find those who had received a hip implant were slightly more likely to have certain types of cancer, such as prostate cancer, melanoma, and a type of bone cancer called multiple myeloma. But they also found that the hip implant recipients were less likely to get stomach cancer.

This is the largest study ever done looking at the association between hip implants and cancer, and the researchers say, "Overall, the results of our study are largely reassuring that hip implants patients have similar rates of most types of cancer as the general population."

However, they do recommend that further medical research be done looking at the possible association between hip implants and certain types of cancer, although this may very well be a false finding.
