Metal-on-metal hip replacements don't increase cancer
After recent concerns about occasional harmful effects from one of the most common types of artificial hip joints, a new study is offering some reassurance: people with metal-on-metal hip replacements are no more likely to develop cancer within seven years of having the hip replacement surgery than the general population. The findings are published in the April issue of the British Medical Journal. This is encouraging to those concerned that the metal in these artificial joints may get into a person's bloodstream and cause illness. Occupational health research has shown an association between exposure to metal ions and the development of cancer.
