After some patients have received "metal-on-metal" hip replacements, the cells in their bladders have oddly changed. Now, early findings from a study suggest that the risk of cancer and genetic damage could increase from the devices.
When friction between the metal ball and cup in the replacement causes tiny metal filings to break off, problems occur. The tiny fragments can seep into patients blood and cause inflammation, which can destroy bone and muscle.
The risk of cancer can increase if there are metal traces in the blood. It can slowly poison major organs, such as the kidneys and bladder.
The British study on 72 patients revealed that bladders of 17 people received genetic damage. Three of those developed cancer.
It is advised that those with the "metal-on-metal" devices should undergo scans and blood tests if their doctors find symptoms that could account for metal leakage.
