Numerous studies linking RFID implants to cancer in animals, are gaining significant attention

Last week, Dailytech reported that California's State senate had blocked employers from requiring their employees to get "chipped"--implanted with an RFID chip that would allow for radio identification and tracking.

Now in addition to the privacy concerns, a new report by the Associate Press has brought to light serious doubts on RFID implants' medical safety.

The report details how numerous studies on RFID implants in animal test subjects, starting in the mid-1990s, revealed that the implants led to a significant increase in malignant tumor growth.

Keith Johnson, a retired toxological pathologist who led one of these studies, in 1996 at Dow Chemical Co., when interviewed in the report stated that he had no doubts about whether RFID was to blame for the increased incidence of cancer.  He is quoted as clearly stating, "The transponders were the cause of the tumors."

The findings were reviewed by top cancer specialists, who found the results disturbing.  They cautioned people that these tests were performed on animals, so that they were not necessarily applicable in humans, however, most felt additional research was a necessity.  Some went as far to say that they would not allow family members to receive implants.

Currently about 2,000 people worldwide have received RFID chips implants, according to VeriChip, the leading manufacturer of FDA-approved RFID implants, including a couple who were ordered to do so by their employer.

Verichip commented that they were "not aware of any studies that have resulted in malignant tumors in laboratory rats, mice and certainly not dogs or cats."

The company also, sells RFID chips for animals.

A significant detail to these studies is that many of them were not intended to study the correlation between RFID chip implanting to cancer--rather, during research on a separate topic the increased cancer rates were high enough to catch the researchers' attention and allow them to draw a clear conclusion that the chip was causing the increased cancer rate.

The AP report goes on to discuss the suspect nature of the FDA's approval of VeriChip's human RFID implant.  The FDA is overseen by the Department of Health and Human Sciences, which at the time of the approval, was headed by Tommy Thompson.

Just two weeks after the Jan. 10, 2005 approval of the device, Tommy Thompson resigned his post with the department and within five months assumed a position at VeriChip.  He received stock options and cash compensation for his newly acquired position.

Thompson, until recently a candidate for the 2008 Republican presidential nomination, recently denied in an interview having any familiarity with VeriChip before his resignation.

The FDA refused to comment on which studies it reviewed when approving the device.

A recent AMA report which lauded RFID implants, claimed to be entirely unaware of the studies correlating the implant to cancer.  Dr. Steven Stack, an AMA board member, said he had never heard the studies ever mentioned before.

As Dr. Stack had knowledge of the Department of Health and Human Sciences committee's review of the implant, pending FDA approval, this statement would indicate that the Committee did not take these studies into account during its approval process.

More research needs to be done before final conclusions are drawn, but as its dirty laundry comes to light, the controversial practice of RFID implanting and its FDA approval has received another major setback.

> "the authors of the study started it after being contacted by a person whose dog (a pet) died of chip related tumor growth."

Read the article again. The "author" in question wasn't the author of a study. It was Katherine Albrecht, the author of the book "Spychips", and a long-time foe of Verichip and implantable chips in general. Until she starts giving some hard facts, I'll take her "chip-induced cancers" with a very large grain of salt.

After all, there are medical items which have long been implanted in the human body. Certainly a glass capsule is inert. So what does that leave? The RF itself...but we all have much stronger RF signals passing through our bodies at all times. For anyone in an urban settings, we have RF doses millions of times stronger striking us 24 hours a day...not just for a couple seconds when an RF tag is scanned.

So in general, I'd be very suspicious of such claims until some hard evidence comes out. Right now, it has all the hallmarks of yet another media-induced scare story, in the likes of Alar and a hundred others.

Yeah I find it hard to believe that a low energy device like an RFID chip could cause cells to mutate. Nor would glass. We've got pace makers keeping hearts beating, screws keeping bones together, metal plates over holes in people's heads, etc. You're telling me a tiny glass capsule is going to cause problems but none of the other things are?

One thing to consider, is that the chip is a tranmiter of electomagnetic radiation, 24/7, 365 days a year. Granted, higher frequency/amplitude cell phone have not caused cancer, but those devices are used externally and not always on. This device is inside the animal (humans included). There should be concern for mutution due to constant, wholly contained exposure

RFIDs do not have an internal power source. They respond only to an external (external to the body in this case) RF signal.

The DO NOT EMIT RADIO FREQUENCY RADIATION unless they recieve the correct signal. Then and only then do they emit and RF signal.

Please, please try to understand the technology.

I believe you are mistaken. Although there is no internal power source, the device is powered by the mechanical to electrical conversion of energy resulting from the patient's natural movements over the course of the day. Just think of the Sharper Image flashlight you shake up and down to power it on. The natural movement allows the VeriChip to send out a continous low-level signal to outside devices, to signal its presence. If the correct signal activates the device, then the transmission of electromagnetic radiation is increased.

There are two types of RFID chips, neither are powered by movement. One has an internal power source, and is called "active", the chip in question has no internal source and only emits radiation when in an electro magnetic field that induces a current. There will not be a cancer risk with the implanted chips in pets because they are rarely if ever activated. In humans, as a method of id, it will be frequently activated. This report is preliminary, and requires serious followup research. Not all RF frequencies are equally mutagenic, this is an important factor. As with all bio dosage, it is the type, amount and frequency that needs to be examined.
