There was a concern that the chips were causing cancer in dogs. You can read the following but it does not concern me anymore. I am still concerned about vaccinations causing cancer but not the chips. I have all of my dogs chipped.

Q: What are some of the problems associated with microchips? How common are they?
A: The British Small Animal Veterinary Association (BSAVA) maintains a database of adverse reactions to microchips. Since the database was started in 1996, over 4 million animals have been microchipped and only 361 adverse reactions have been reported (this represents an incidence of approximately 0.009%). Of these reactions, migration of the microchip from its original implantation site is the most common problem reported. Other problems, such as failure of the microchip, hair loss, infection, swelling, and tumor formation, were reported in much lower numbers. For a chart summarizing the BSAVA reports, read the AVMA's backgrounder on Microchipping of Animals.
Q: I've heard a lot lately that microchips cause cancer. Do they?
A: There have been reports that mice and rats developed cancer associated with implanted microchips. However, the majority of these mice and rats were being used for cancer studies when the tumors were found, and the rat and mice strains used in the studies are known to be more likely to develop cancer. Tumors associated with microchips in two dogs were reported, but in at least one of these dogs the tumor could not be directly linked to the microchip itself (and may have been caused by something else). For more details on the studies, read the AVMA's backgrounder on Microchipping of Animals.
The BSAVA instituted a microchip adverse reaction reporting system in 1996. The following table summarizes the reported types and incidences of microchip-associated adverse reactions in the United Kingdom. (BSAVA, 2007) Over 4 million cats and dogs in the U.K. have been microchipped. (The Kennel Club, 2007)
