Do Animal Computer Chip Implants Cause Cancer?

July 14th, 2009 by Paul Johnson

I recently discovered that chip implants given to rats have been shown to cause malignant tumors in past studies. Chip implants are used in dogs and cats, so if they get lost, a vet can find the rightful owner. There were multiple veterinary and toxicology studies done in the 1990’s supporting evidence that these implants could actually cause dangerous malignant tumors. The FDA has approved the technology, despite this evidence. You may be shocked that the FDA would approve chip implants even for humans with this evidence. You have to realize that the FDA is very corrupt and they allow a lot of unsafe things in our food they shouldn’t. You can read more from a news article on it.

Now some of you dog owners will want to keep track of your dog, but are scared to use chimp implants in your pets after reading this post. The good news is there is a much better alternative to tracking your dogs anyways, called a GPS Dog tracking system. It’s a little box that attaches to the collar and tracks your dogs exact location. Many of the GPS devices for dogs look similiar to the picture below.

There are different types of Dog GPS tracking systems, but with most you pay a subscription per month for the service, usually around 10 dollars. The average GPS tracking system costs about 200 to 500 dollars. When your dog goes missing or leaves a certain pre-defined area than you will get alerted. With most of the GPS tracking system devices you can track the current location of your dog by one or all of the following ways; cellphone, email, internet, and pager.

The downside to these GPS tracking devices compared to the chip implants is that they usually require a monthly subscription and are expensive to buy. However, they are better than the regular chip implants because the implants won’t tell you the exact location of your dog like these GPS tracking devices. The chip implants are only useful when your dog is found by a vet and are checked by their chip reader. The chip implants are not a GPS tracking device. The chip implant only identifies who is their dog owner. The vet must use a chip reader to find out if a dog has a chip embedded in him and then it reads the contact information stored on the chip. A reasonable priced Dog GPS system is the PetSafe GPS Pet Locator sold at

    Thanks for the info on the chips. I didn’t know the risks. I’ll look into the GPS locator cause those look safe.

    Please let me know as well where to get an ID chip removed from. My vet says they can not remove it , due to it travels within the body. Which is a question I asked them before I had the chip implanted. They said it does not , but now they want to change their story. I am concerned due to the fact, over the past two weeks my cat has developed epilepsy and was having seizures, but they are now controlled by medication.

    Hi Erin,

    My vet told me the same thing about the implant chip in my cat. In fact, I told them not to implant a chip yet they did it anyways. What is wrong with this picture? Why implant a chip in an animal when it can’t be removed? What happened to freedom to choice for you and your pet?

    GPS attached to a collar won’t help if your dog loses his collar. After our dog got out of our yard through a loose picket in the fence, he somehow somewhere lost his collar. We got him back only because the person who found him saw the “Lost Dog” signs we put up. We had him chipped that very week, although we didn’t know about the potential cancer risk at the time. However, I would do the same thing today, knowing what I know, because the risk of death when a pet is lost is too great.

    We implanted our cat in the States as a requirement to transport him to Germany to be with us. He was perfectly healthy in July 2011, when he was implanted. Now, in November 2011, he has a huge tumor between his lungs and stomach, AND he has spots in his lungs. In addition, the tumor is “aggressive,” and it’s attacking his nerves and muscles…this means that he walks like he’s drunk, and he’s chewing on his paws in reaction to the pain. We’re using steroids and pain medicine to see if it helps, to buy some time. If not, we’ll have to put him down….and he was a healthy, active cat.

    In essence, by implanting the chip, we killed him. 🙁
