In the field of cancer research, there have been many benefits resulting from animal testing. The Americans for Medical Progress website states: "Thanks largely to animal research, there is a new molecular and genetic understanding of tumor biology, leading to treatments that aim to more directly kill tumor cells, which are molecularly different from the normal ones". cells. Using this knowledge to design drugs that target such abnormalities is called rational drug design and is seen by many as the currently emerging future reality of cancer treatment – ​​of “kinder, gentler” cancer therapies that target only the abnormal cells” (1) . It is arguable that these advances in medical research could have remained hidden for a longer or even permanent period if it were not for the help of tests carried out on
