Microchips Cause Cancer? I'd Like A Bit More Information

A series of veterinary and toxicology studies, dating to the mid-1990s, stated that chip implants had "induced" malignant tumors in some lab mice and rats. "The transponders were the cause of the tumors," said Keith Johnson, a retired toxicologic pathologist, explaining in a phone interview the findings of a 1996 study he led at the Dow Chemical Co. in Midland, Mich. "We stand by our implantable products which have been approved by the FDA and/or other U.S. regulatory authorities," Scott Silverman, VeriChip Corp. chairman and chief executive officer, said in a written response to AP questions. The company was "not aware of any studies that have resulted in malignant tumors in laboratory rats, mice and certainly not dogs or cats," but he added that millions of domestic pets have been implanted with microchips, without reports of significant problems.

This is quite alarming. Saying you are "not aware of any studies" isn't the same thing as saying that they don't increase the risk of cancer. I think there is enough circumstantial evidence to warrant some concern. Time for a study on pets to determine the actual risk, eh?
