cancérogène

A carcinogen is any substance, organism, or agent that causes cancer. This can happen through damage to a cell's DNA or by interfering with the cell's normal biological processes. Carcinogens can be found in the environment, in food and drink, and in products we use.

Exposure to carcinogens can occur through various routes, including inhalation, ingestion, and skin contact. The risk of developing cancer from exposure depends on several factors, such as the type of carcinogen, the duration and level of exposure, and individual susceptibility. Some carcinogens are more potent than others, meaning a lower level of exposure can lead to a higher risk.

Common examples of carcinogens include tobacco smoke, asbestos, certain viruses like HPV, ultraviolet radiation from the sun, and some chemicals found in industrial settings. Public health organizations and regulatory bodies work to identify and regulate carcinogens to protect human health. This often involves setting exposure limits, providing guidelines for safe handling, and raising public awareness. Research into the mechanisms by which carcinogens cause cancer is ongoing, aiming to develop better prevention and treatment strategies.
