PETS DEVELOP FAST-GROWING,
Medical Reports Point to Link Between RFID Chips and
Cancers in Canines
aggressive tumors developed around the microchip implants of
two American dogs, killing one of the pets and leaving the other
terminally ill. Their owners --- and pathology and autopsy reports
--- have suggested a link between the chips and the formation of
the fast-growing cancers.
the town of Paeonian Springs, Va., a five-year-old male
Bullmastiff named Seamus died in February, nine months after
developing a "hemangio-sarcoma" --- a rare, malignant form of
cancer that strikes connective tissues and can kill even humans in
three to six months. The tumor appeared last May between the dog's
shoulder blades where a microchip had been implanted; by September,
a "large mass" had grown with the potential to spread to the lungs,
liver and spleen, according a pathology report from the Blue Ridge
Veterinary Clinic in Purcellville, Va.
scheduled to receive just a biopsy, Seamus underwent
emergency surgery. A foot-long incision was opened to extract the
4-pound-3-ounce tumor, and four drains were needed to remove fluid
where the tumor had developed.
Howard Gillis, the dog's owner, picked up his pet the
following day, the attending veterinarian stunned him with this
question: Did you know your dog had been microchipped twice, and
that both chips were in or around the tumor?
we knew of one chip, which we had put in him at a free local
county clinic, we knew nothing of a second chip," Gillis said. "We
believe one of them was put in Seamus by the breeder from whom we
bought him when he was about nine months old."
December, the cancer was back --- and the energetic, playful
150-pound dog was huffing and puffing, struggling to walk. Seamus
"was 150 pounds of heart," Gillis said in a recent interview. "He
wanted to live."
said he "got the microchip because I didn't want him stolen.
I thought I was doing right. There were never any warnings about
what a microchip could do, but I saw it first-hand. That cancer was
something I could see growing every day, and I could see it taking
his life ... It just ate him up." To keep his beloved dog from
suffering further, he had him put to sleep two months later.
a five-year-old Yorkshire Terrier named Scotty was
diagnosed with cancer at the Cloverleaf Animal Clinic in December.
A tumor between the dog's shoulder blades --- precisely where a
microchip had been embedded --- was described as malignant
lymphoma. A tumor the size of a small balloon was removed; encased
in it was a microchip.
was given no more than a year to live.
the dog's owner, Linda Hawkins, wasn't satisfied with just a
prognosis: She wanted to know whether the presence of the microchip
had anything to do with Scotty's illness. Initially, her
veterinarian was skeptical that a chip implant could trigger
cancer; research has shown that vaccine injections in dogs and cats
can lead to tumors.
a December pathology report on Scotty, Evan D. McGee wrote: "I
was previously suspicious of a prior unrelated injection site
reaction" beneath the tumor. "However, it is possible that this
inflammation is associated with other foreign debris, possibly from
the glass-encapsulated tag under a microscope, he noted
it was partially coated with a translucent material, normally used
to keep embedded microchips from moving around the body. "This
coating could be the material inciting the inflammatory response,"
sent the pathology report to HomeAgain, the national pet
recovery and identification network that endorses microchipping of
pets. After having a vet review the document, the company said the
chip did not cause Scotty's tumor --- then in January sent Hawkins
a $300 check to cover her clinical expenses, no questions
find it hard to believe that a company will just give away $300
to somebody who calls in, unless there is something bad going on,"
spent $4,000 on medical treatment for Scotty since December,
Hawkins accepted the money. But she says it hardly covers her $900
monthly outlays for chemotherapy and does little to ease her pet's
is just a baby. He won't live the 15 years he's supposed to
...I did something I thought a responsible pet owner should ---
microchip your pet --- and to think that it killed him ... It just
breaks your heart."
and Seamus aren't the only pets to have suffered adverse
reactions from microchips. Published reports have detailed
malignant tumors in two other chipped dogs; 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.
a Chihuahua bled to death in the arms of his distraught
owners in Agua Dulce, Calif., just hours after undergoing a
chipping procedure. The veterinarian who performed the chipping
confirmed that dog died from blood loss associated with the
another case, a kitten died instantly when a microchip was
accidentally injected into its brain stem. And in another, a cat
was paralyzed when an implant entered its spinal column. The
implants have been widely reported to migrate within animals'
bodies, and can cause abscesses and infection.
2007, The Associated Press reported on a series of veterinary
and toxicology studies that found that microchip implants had
"induced" malignant tumors in some lab animals. Published in
veterinary and toxicology journals between 1996 and 2006, the
studies found that between 1 and 10 percent of lab mice and rats
injected with microchips developed malignant tumors, most of them
encasing the implants.
