October 23, 2012 costs of animal and non-animal testing humane society international some animal tests take months or years to conduct and analyze (eg, 4-5 years, in the case of rodent cancer studies), at a cost of hundreds of thousands—and sometimes millions—of dollars per substance examined (eg, $2 to $4 million per two-species lifetime cancer study. The proposed new approach, using a 2-year rat bioassay supplemented, or replaced, by a 6-month transgenic mouse bioassay, does not really signify a new way of doing things at all since we are still wedded to using a rodent in some shape or form, in an extended testing regime, to assess carcinogenic potential.
