The Associated Press will issue a breaking story this weekend revealing that microchip implants have induced cancer in laboratory animals and dogs, says privacy expert and long-time VeriChip opponent Dr. Katherine Albrecht.

As the AP will report, a series of research articles spanning more than a decade found that mice and rats injected with glass-encapsulated RFID transponders developed malignant, fast-growing, lethal cancers in up to 1% to 10% of cases. The tumors originated in the tissue surrounding the microchips and often grew to completely surround the devices, the researchers said.
