Carcinogenicity is the study of substances or agents that have the potential to cause cancer in humans. This research area involves identifying and evaluating the carcinogenic properties of various compounds, such as chemicals, drugs, radiation, and environmental pollutants. Researchers in this field aim to understand the mechanisms by which carcinogens induce cancerous changes in cells and tissues, as well as to assess and mitigate the risks associated with exposure to these substances. Studies in carcinogenicity may involve experiments on cell cultures, laboratory animals, and epidemiological investigations in human populations. The ultimate goal of this research is to inform public health policies and regulations to protect individuals from cancer-causing agents.
