FAQ
Frequently Asked Questions
Not exactly. All carcinogens are toxic in the long-term sense, but not all toxins/poisons are carcinogens. A carcinogen specifically causes cancer, while a toxin may cause other types of acute or chronic harm (e.g., liver damage, nerve damage) without necessarily causing cancer.
No. Cancer development depends on many factors: the dose and duration of exposure, individual genetics, the presence of other risk factors, and the body's ability to repair damage. A carcinogen increases the risk or probability.
Common examples include tobacco smoke (containing many carcinogens), ultraviolet (UV) radiation from the sun, asbestos fibres, alcohol (in excessive amounts), certain components of processed and red meats, and some industrial chemicals like benzene and formaldehyde.
Organizations like the International Agency for Research on Cancer (IARC) classify them into groups: Group 1 (Carcinogenic to humans), Group 2A (Probably carcinogenic), Group 2B (Possibly carcinogenic), Group 3 (Not classifiable), and Group 4 (Probably not carcinogenic).
