Genotoxicity is the study of the potential damage that certain chemical substances or agents can cause to the genetic material within cells. This damage can lead to mutations, chromosomal abnormalities, or other types of genetic damage, which in turn can increase the risk of diseases such as cancer. Genotoxicity studies are commonly conducted in toxicology research to assess the safety of chemicals, drugs, and other substances. These studies typically involve various tests that evaluate the ability of a substance to cause DNA damage and genetic mutations in cells. The findings of genotoxicity studies are important for regulatory agencies to determine the potential risks associated with the exposure to certain chemicals or substances.
