The medicine used to test on animals causes side effects different from humans. When researchers inject the drug they are required to observe the side effects that is happening to the animal and later predict the side effects that will happen on a human. In an article by Pat Thomas states: the drug Tamoxifen used for breast cancer treatment was tested on rodents. The drug when used on rodents reduced the chances of mammary cancer, but it increased the chances for liver cancer. While on humans Tamoxifen increased the chances for uterine cancer (Source A). The researchers thought the drug Tamoxifen would increase the chance of liver cancer on humans just like it did on rodents, but their predictions were incorrect. Because of the drug used to test on animals the predicted side effects on humans …show more content…
Researchers need to test medicine using advanced technology not on animals. All researchers around the world need to find a safer more accurate way to test medication. If researchers keep using animals, their results will always be different for humans and they will never find a solution that will help people with their health. There are ways to test medication that are safer, faster, and cheaper than animal testing. If researchers use the technology animal testing will be eliminated from
