From what I have read the risk to pets seems to be insignificant in the study. I believe, at this point, the benefits out way the risks of cancer. I mean, what’s next? Should we all go live on an island somewhere where there are no cellphones, plastic containers, computers, TVs, foods and even the air that we breathe, which are all linked to causing cancer.

The Associated Press is reporting that a series of studies dating to the 1990s–and largely unpublicized –indicated a possible link between microchips in some lab mice and rats and cancer. Some 2,000 microchips have been implanted in humans worldwide, but millions of dogs and cats have been microchipped, raising worries about the implants’ safety (as well as how the U.S. Food and Drug Administration approved implanting the chips in humans in 2005.
VeriChip Corp., the Florida company that makes the chips, says they are safe. Chairman and CEO Scott Silverman says management wasn’t aware “of any studies that have resulted in malignant tumors” in lab animals. He also pointed out that millions of pets have had chips implanted without reports of significant problems.
But the AP has found several studies that do show an increase of tumors that were attributed to the chips.
Dr. Cheryl London, a veterinarian oncologist at Ohio State University, says that veterinary pathologists haven’t reported a jump in cancerous tumors from the chips. She suggested, though, the need for a 20-year study of chipped dogs. And Dr. Chand Khanna, a veterinary oncologist at the National Cancer Institute, concurred with that recommendation, saying current evidence “does suggest some reason to be concerned about tumor formations.”
After reading the AP story, do you have second thoughts about getting your pet microchipped?
Praised as an innovative new technology upon their invention, microchips containing an individuals medical history seemed the wave of the future. However, after being approved by the U.S. Food and Drug Administration, the chips have been linked to cancer in a series of recent studies. Many of these chips, called radio frequency identification, or RFID, have been placed in animals as a tracking device, to help retrieve lost pets. Both the manufacturer and regulator failed to disclose that toxicology and veterinary reports from the mid 1990’s showed that the chip had “induced” cancerous tumors in lab animals. In the studies published in veterinary journals from 1996 to 2000, it is reported that malignant tumors were found in mice and rats injected with the microchips. Most of these tumors were found encasing the implants. Dr. Katherine Albrecht, founder and director of Consumers Against Supermarket Privacy Invasion and Numbering, said that her organization “would like to see microchipping become like
smoking. If a person desires to have a chip implanted they should have the right to, but should know they are potentially unhealthy.” According to ISU professor of Politics and Government Bob Bradley, the ethical debate over whether chips should be implanted in humans, focuses on one central question, “What will be used with the obtainable information?” Bradley elaborated about the tracking capabilities of RFID, “it cuts into the notion of self-autonomy, or the idea that we can do what we want, when we want to do it.”CASPIAN is currently working towards introducing a bill in state congress’ called the “Bodily Integrity Act.” This bill aims to establish laws making mandatory chip implants illegal, and tracking of an individual illegal without expressed consent of that individual. The chip itself is about the size of a grain of rice and can be injected easily without any anesthesia. Each chip has its own unique number, and can never be altered. In animals the chip sends out its unique signal, which can be used to help locate lost animals.
Bloomington veterinarian Dr. Greg Tackett DVM, of the Eastland Companion Animal Hospital, stated that his clinic had implanted hundreds of AVID chips over the years and had not seen any malignancies result to date. Though the AVID chip is not the chip being investigated, the proprietary technology of that chip and the VeriChip, which is being placed in humans, is the same. According to Jennifer Wake, shelter manager for the Humane Society of Central Illinois, the most common problem associated with the chips is a “migrating” chip, or a chip that has come out of place. The Humane Society, located in Bloomington, has been implanting animals for the past two years. In research for the Associated Press cancer specialists indicated that tumors in animals do not necessarily mean the same will happen to humans. Additionally, they cautioned against using the technology without further research.Only a small number of people have been implanted with RFID chips, about 2,000 worldwide. These chips, when scanned, send their unique number to the scanner, which retrieves the carrier’s medical history.
