Carcinogens are agents that have the potential to cause cancer. Exposure to carcinogens can increase the risk of developing malignant tumors. These agents can be found in various environments, including nature, the workplace, and everyday products.

Common examples of carcinogens include certain chemicals, radiation, and infectious agents. Tobacco smoke is a well-known carcinogen, containing numerous harmful compounds. Asbestos is another significant carcinogen, particularly linked to mesothelioma and lung cancer when inhaled. Certain types of radiation, such as ultraviolet (UV) radiation from the sun and ionizing radiation from X-rays or nuclear sources, are also classified as carcinogens. Some viruses, like the human papillomavirus (HPV) and hepatitis B virus, have been identified as carcinogens due to their association with specific types of cancer.

The mechanism by which carcinogens cause cancer often involves damage to a cell's DNA. This damage can lead to mutations that disrupt normal cell growth and division, ultimately resulting in uncontrolled proliferation of abnormal cells. The effect of a carcinogen can depend on various factors, including the type of carcinogen, the dose and duration of exposure, and individual susceptibility.

Identifying and regulating carcinogens is a crucial aspect of public health. Organizations like the International Agency for Research on Cancer (IARC) and national regulatory bodies work to classify agents and establish guidelines to minimize exposure and protect populations from cancer risks. Prevention strategies often focus on reducing or eliminating exposure to known carcinogens in environments and products.
