In November 2001 (19 months later) the dog’s owner detected a firm, painless lump at the implant site measuring 10 x 6 cm (approximately 4 x 2.5 inches). The location is right, and it's certainly not uncommon to be able to palpate an implanted chip - I can feel Corona's and Aria's. The CD-1 (albino) mouse is described as a “general multipurpose model [for] safety and efficacy testing, aging, surgical model, [and] pseudopregnancy” (Charles River Laboratory, 2007, p. 15). It appears that few people undergoing microchip implantation have been told about the potential health risks associated with the device. A similar observation was made by Le Calvez et al. 1999;27(5):519 -527, There was an unequivocal association between the [microchip implant] transponder and sarcoma that was unrelated to drug treatment.

If the lump contains cancerous or pre-cancerous cells, it may need to be surgically removed. The microchip is implanted into dogs through an injection procedure involving a 12-gauge needle. Table 1 lists the cancer incidence from eight studies where cancer was found in connection with a microchip implant. [and] a diagnosis of low-grade liposarcoma was made.

Smaller tumors in the early stages of development that were not yet visible to the naked eye may have been missed. As a dog ages, they often develop spongy lumps, called lipomas, on their bodies. The investigators conclude by stating that “reports on adverse reactions to vaccination and microchips are strongly encouraged to deepen the current knowledge on their possible role in tumorigenesis [causing tumors],” calling it “a matter of discussion for experts” (p. 547). If it is about the size of a grain of rice, that's the chip. I've never heard of that and I've worked for more than 15 vets. First, the immune system can become active at the site of the injection, causing an infiltration of immune cells that leads to a small lump. The move to introduce compulsory microchipping fills the gap left after dog licences were abolished in the United Kingdom in 1988. (p. 258), One of the most potentially serious disadvantages of the microchip implantation is the possibility that foreign-body-induced tumours may develop … (p. 256). To start viewing messages, select the … In addition to the six studies that identified cancer in rodents, two studies evaluated cancerous tumors (fibrosarcoma and liposarcoma) that developed in dogs at the site of microchip implants. The tumors generally occurred in the second year of the studies, or after half a lifetime’s exposure to the implant. I discovered today that Pebbles has a round lump on her right side on the muscle of her back.
