Does Animal Testing Help Human Medicine?

33 Facts to be Considered

(1) Less than 2% of human illnesses (1.16%) are ever seen in animals.
(2) According to the former scientific executive of Huntingdon Life Sciences, animal tests and human results agree only "5%-25% of the time".
(3) 95% of drugs passed by animal tests are immediately discarded as useless or dangerous to humans.
(4) At least 50 drugs on the market cause cancer in laboratory animals. They are allowed because it is admitted the animal tests are not relevant.
(5) Procter & Gamble used an artificial musk despite it failing the animal tests, i.e., causing tumours in mice. They said the animal test results were "of little relevance for humans".
(6) When asked if they agreed that animal experiments can be misleading "because of anatomical and physiological differences between animals and humans", 88% of doctors agreed.
(7) Rats are only 37% effective in identifying what causes cancer to humans. Flipping a coin would be more accurate.
(8) Rodents are the animals almost always used in cancer research. They never get carcinomas, the human form of cancer, which affects membranes (e.g lung cancer). Their sarcomas affect bone and connecting tissue: the two cannot be compared.
(9) Up to 90% of animal test results are discarded as they are inapplicable to man.
(10) The results from animal experiments can be altered by factors such as diet and bedding. Bedding has been identified as giving cancer rates of over 90% and almost nil in the same strain of mice at different locations.
