Dogs Suffer Cancer After ID Chipping

Do implanted microchips cause cancer in dogs and cats?

That's the question owners are asking after highly aggressive tumors developed around the microchip implants of two dogs, killing one and leaving the other terminally ill. The owners, as well as pathology and autopsy reports, suggest a link between the chips and formation of fast-growing cancers.

Dr. Katherine Albrecht has authored a 52-page peer-reviewed article, titled "Microchip-Induced Tumors in Laboratory Rodents and Dogs: A Review of the Literature," in which she discusses literature published in oncology and toxicology journals between 1990 and 2006 that address the effects of implanted radio-frequency microchips on laboratory rodents and dogs.

She said it is important that the public be made aware of the potential hazards of microchipping because some governments are seeking to make dog chipping mandatory. For example, the British government recently announced its proposal to impose penalties on pet owners who do not comply with chipping requirements. Ireland, New Zealand, Malta, Norway, Switzerland, Austria, Croatia, Italy and Portugal and even some places in the United States require mandatory microchipping.
