Patients who received metal-on-metal hip replacements are at no greater risk of developing cancer after a seven-year period than those with alternatives or the general population, according to a study.
A longer-term review is needed of the effect of metal particles leaking from the implants, because some tumors take many years to develop, according to the research published in the British Medical Journal today. Investigators looked at the incidence of malignant melanoma as well as hematological, prostate and renal tract cancers, which are associated with metal ions in the body.
