Analgesic Use Associated With Increased Risk For RCC.

MedPage Today  (10/29, Bankhead) reported, "Analgesic use increased the hazard for renal cell carcinoma (RCC) by as much as 33%, depending on the drug class," according to research presented at the American Association for Cancer Research Frontiers in Cancer Prevention Research meeting. "Use of acetaminophen or nonaspirin, nonsteroidal anti-inflammatory drugs (NSAIDs) significantly increased the risk of RCC compared with nonuse. Aspirin use was not associated with an increased risk of the kidney cancer," researchers reported. To reach these conclusions researchers examined data from18 studies.
