FDA links TNF blockers to cancer in children

The U.S. Food and Drug Administration is requiring that TNF blockers have a warning added to their labels indicating an increased risk of cancer in children. "An analysis of U.S. reports of cancer in children and adolescents treated with TNF blockers showed an increased risk of cancer, occurring after 30 months of treatment on average. About half of the cancers were lymphomas, a type of cancer involving cells of the immune system. Some of the reported cancers were fatal." More information from Newsday, the Wall Street Journal and WebMD.
