MicrochipWell according to some of the latest information that seems to be the case, at least in laboratory studies. To quote – “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.”

Pet owners and lovers have been implanting these in their dogs and cats for years and this is the first I’ve heard of this. Ever since I’ve heard of microchipping, I’ve been a strong proponent of it, especially after hearing story after story of pets being reunited with their owners due to this technology. Both my dogs, Jezzie and Bruti, are ‘chipped.

It seems that the company, VeriChip, wants to implant these microchip in people for medical reasons and the push must be on for all of this to be coming out now.

When the U.S. Food and Drug Administration approved implanting microchips in humans, the manufacturer said it would save lives, letting doctors scan the tiny transponders to access patients’ medical records almost instantly. The FDA found “reasonable assurance” the device was safe, and a sub-agency even called it one of 2005’s top “innovative technologies.”

But it seems that no one told the FDA or the public about the fact that in studies these little implants caused ‘malignant tumors.”

To date, about 2000 of these have been implanted in people but the company sees a target market of 45 million!

“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.

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.

Although published in veterinary and toxicology journals between 1996 and 2006, the studies found that lab mice and rats injected with microchips sometimes developed subcutaneous “sarcomas” malignant tumors, most of them encasing the implants, the AMA (American Medical Association) claims to have been unaware or the studies.

Different studies showed between a 1% and 10% cancer rate in mice injected with the implants and some of these studies were not even on the implants themselves, the findings were incidental.

Although these microchips have been implanted in tens of thousands of dogs, there has been no reported outbreak of tumors showing up related to the implants. “Published reports detailing malignant tumors in two chipped dogs turned up in AP’s four-month examination of research on chips and health. In one dog, the researchers said cancer appeared linked to the presence of the embedded chip; in the other, the cancer’s cause was uncertain.”

But who knows what we’ll see in the canine population in another ten years? With the fact that these ‘chips reunite literally thousands of dogs and pets with their owners monthly, I do not regret having my babies implanted with them, but this information has made me aware that I will need to be vigilant and keep an eye on the implant area. At this point the risk seems very small and the payoff, if one of my dogs ever gets away from me or lost, seems very large.
