Have you read the articles that you linked? The TVP article you linked states, and I quote, "Tumors also occur secondary to injections of steroidal and nonsteroidal anti-inflammatory drugs, antibiotics, and lufenuron; microchip implantation; and inflammatory response to nonabsorbable surgical suture material."
Please read the article thoroughly. It is very clear about the fact that the sarcomas are related to the injection, not to the contents of the injection. Gee, even sutures cause the type of oxidative stress injury that (rarely) induces a sarcoma.
Sorry. I said you mixed fact & fantasy not based on incidence but on all your other inventive assertions. Don’t quit the day job.
