Browsing: Carcinogens

Carcinogens are substances, agents, or exposures that can cause cancer by altering cellular metabolism or damaging genetic material (DNA) within cells, leading to uncontrolled cell growth. These cancer-causing agents can be chemical, physical, or biological in nature. Examples of chemical carcinogens include tobacco smoke, asbestos, and certain industrial chemicals like benzene. Physical carcinogens include radiation, such as ultraviolet (UV) rays from the sun or ionizing radiation from X-rays. Biological carcinogens include certain viruses, such as human papillomavirus (HPV) and hepatitis B, which are linked to cervical and liver cancers, respectively. Carcinogens may not cause cancer immediately but can increase the risk over time, especially with prolonged or repeated exposure. Identifying and reducing exposure to carcinogens is a critical aspect of cancer prevention efforts globally.
