Anything can cause cancer....even water.
Lest we forget age as a cause if one is blessed with becoming aged.
A friend of ours works at Ft Detrick and his job involves lab animals, exclusively.
As a pet rat owner, he has clarified many of the inherent health problems of my rats for me.
*Most* laboratory animals are ‘designed’ to be more [or, in some cases, less] genetically susceptible to whatever disease they are being used to research.
[think of it as a means of “time compression” to facilitate fast turnaround times to obtain desired research results]
There are many carefully bred and controlled “strains” of lab rats and mice, each with a different research purpose and biological/genetic disposition.
Most of these strains of lab animals are actually -patented- because of the predictability of their susceptibility to “[fill in the blank] disease”.
-Every- white [or dilute colored or predominantly white with spots] rat I’ve ever owned was obese, despite careful dietary management.
They are “programmed” to be obese because they are used primarily for obesity and cardiac studies.
The dark rats [ones that looked more like “real rats] had no obesity and much longer life spans.
Others are programmed for cancers, sometimes very specifically.
Test “results” based on these artificially created rodents do not really relate to the reality of human [or dog] disease ratios.
Microchips have been used in dogs for a very long time now and barring the previous problem with migration [a problem now “fixed”], there have been no untoward tendencies or spikes in correlated cancer rates for microchipped dogs.
There are, however, due to careless breeding programs, now many breeds with heavy tendencies to develop devastating cancers, Rottweilers and bone cancer, being just one case that comes to mind.
This “microchip mouse tumor revelation” first appeared in my email inbox back on October 2 of 2006.
It’s old news being recycled into a new panic meme.
