Has anyone tagged their pet with a RFID chip and then they developed tumors?

After implanting the RFID chip in my Parsons Jack Russel Terrier, he developed six "fast growth carcinomas" within eight weeks. Five of them were within four inchesof the implant site. After researching the review process conducted by the FDA and the relationship between the manufacturer and a Bush appointee, I am led to believe that there is far more to the story than initially thought. Can anyone share with me any insight they may have?
