A few scientists speak up about this again and again. For example, Dr. Richard Klausn; former director of the National Cancer Institute in the USA (NCI), who in an article in the Los Angeles Times in 1998 stated: »The history of cancer research has been a history of curing cancer in the mouse. We have cured mice of cancer for decades – and it simply didn't work in humans.« His colleague, former director of the Sloan-Kettering Cancer Research Institute, Dr. Irwin Bross, stated this somewhat more precisely already in 1981 before the US Congress: »The uselessness of most of the animal model studies is less well known. For example, the discovery of chemotherapeutic agents for the treatment of human cancer is widely-heralded as a triumph due to use of animal model systems. However, here again, these exaggerated claims are coming from or are endorsed by the same people who get the federal dollars for animal research. There is little, if any, factual evidence that would support these claims. Indeed, while conflicting animal results have often delayed and hampered advances in the war on cancer, they have never produced a single substantial advance either in the prevention or treatment of human cancer. For instance, practically all of the chemotherapeutic agents which are of value in the treatment of human cancer were found in a clinical context rather than in animal studies. «
The endless millions of animals that were killed in the search for new means of fighting cancer were thus sacrificed for nothing.«
