British-based website Scientist Live reports on a possible link between cancer and the use of thiazolidinediones (TZDs), a class of medications used to treat diabetes. The link comes from the Vermont Diabetes Information System, which enrolled just over one thousand participants in a study that relied on self-reported patient information and lab-verified data. The authors of the study assert that the link between TZD use and increased incidence of cancer is significant even after correcting data to allow for the influence of other factors such as smoking, body mass index, and other drugs being taken by the patients.A little background: TZDs are prescribed because they lower blood sugar levels. They work by lowering insulin resistance, making the body better able to respond to insulin without actually causing an increase in insulin production. Brand name examples of TZDs include Actos, Avandia and Metformin. A type of TZD medication was banned in Europe after it was found to cause severe liver damage. According to the Wikipedia entry on TZDs, these substances are being investigated as potential treatments for a handful of other medical problems, but are currently used just for diabetes.
If there is indeed a link between TZD usage and increased cancer risk, we really need to find out ASAP. These drugs are prescribed to treat a chronic condition, so once you're on one you're likely to stay on it long-term. Who wants to be exposed to that on top of all the other possible side-effect risks? Stay tuned.

Although the United States clearly takes the cake (and devours every last piece of it) as the fattest country in the world, there are many European nations who also seem to be indulging a bit too much these days. With cases of type 2 diabetes being diagnosed concurrently with rising obesity rates, this is clearly an issue that deserves worldwide attention.
