Before entering every new substance - either edible or hygienic, and especially medicines and toxins – into the distribution cycle, it is urgent and necessary to do detailed tests to challenge its safety in use and the side effects of that material. One of these tests is related to the cancerogenity of the substances, which are done until now based on the international protocols that are called: classic tests. Concluding my research in the University of Hamburg in Germany, it was clear that these experiments are not conclusive. There was known substances which are proved to be cancerogenic and highly risky, but they are entered in the consumption cycle in the world. Research showed that a non-classical mechanism helps these materials to produce cancer. This machanism was modeled, and it is suggested to use non-classical tests in the safety experiments of materials.
