The chips, which are currently being injected into US soldiers, have been causing cancer in lab rats and mice.
Malignant tumours, sometimes encased the implants, AP hacks claimed.
The experts point out that there is a considerable difference between humans and animals. It's easier to cause cancer in a lab mouse than a human. But they think that there needs to be some more long term controlled studies to be done on RFID chips in larger animals and possibly humans.
The devices used in humans are made by VeriChip which has installed 2,000 chips worldwide. It wants to use them to provide medical monitoring in 45 million Americans.
VeriChip chairman Scott Silverman said that he didn't know about any studies that "resulted in malignant tumors in laboratory rats, mice and certainly not dogs or cats."
Millions of pets have RFID implants and there have been no reports of significant problems, he said.
Silverman missed studies conducted in 1996 by toxicologic pathologist Keith Johnson at the Dow Chemical, another by study conducted in Germany in 1997, another in the US and one France. All say RFID chips caused cancer in animals. We understand Silverman's problem. You never have enough time to read everything that comes your way.
