Chemical and Biological Carcinogens Quiz

Chemical Carcinogens

• Asbestos: Known for causing mesothelioma and lung cancer.
• Benzene: Strongly linked to leukemia and various blood cancers.
• Formaldehyde: Associated with nasopharyngeal cancer and leukemia.
• Vinyl Chloride: Causes angiosarcoma of the liver, a rare form of liver cancer.
• Aflatoxins: Fungal byproducts that increase the risk of liver cancer.
• Polycyclic Aromatic Hydrocarbons (PAHs): Found in tobacco smoke, charred meats, and vehicle exhaust; linked to cancers of the lung, skin, and bladder.
• Arsenic: Associated with skin, lung, and bladder cancers.
• Cadmium: Recognized as a significant risk factor for lung cancer.
• Chromium VI: Known carcinogen that primarily causes lung cancer.
• Nitrosamines: Present in tobacco products and processed meats; linked to stomach and esophageal cancers.

Biological Carcinogens

• Human Papillomavirus (HPV): Major cause of cervical, anal, and oropharyngeal cancers.
• Hepatitis B and C Viruses: Strongly associated with liver cancer.
• Helicobacter Pylori: Bacteria linked to stomach cancer development.
• Epstein-Barr Virus (EBV): Associated with nasopharyngeal cancer and certain lymphomas like Burkitt lymphoma.
• Human Immunodeficiency Virus (HIV): Increases risk for certain cancers, including Kaposi sarcoma and non-Hodgkin lymphoma, although not directly carcinogenic.

Environmental and Occupational Carcinogens

• Tobacco Smoke: Contains numerous carcinogens, including PAHs and nitrosamines; linked to multiple cancers such as lung and bladder cancer.
• Radon Gas: Naturally occurring radioactive gas that leads to an increased risk of lung cancer.
• Ultraviolet (UV) Radiation: From sunlight; a significant contributor to skin cancers, notably melanoma.
• X-rays and Gamma Rays: Forms of ionizing radiation associated with various cancers, particularly leukemia and thyroid cancer.

Pharmaceuticals and Medical Treatments

• Chemotherapy Drugs: Some agents, particularly alkylating agents, have the potential to cause secondary leukemia after prolonged use.
• Diethylstilbestrol (DES): A synthetic estrogen linked to the development of vaginal and cervical cancers in daughters of mothers who used the drug during pregnancy.

Lifestyle-Related Carcinogens

• Alcohol Consumption: Associated with an increased risk for cancers of the liver, esophagus, breast, and head/neck.
• Processed Meats: High consumption frequency linked to colorectal cancer risk, primarily due to the presence of nitrosamines.

Chemical Carcinogens

• Asbestos: Causes mesothelioma and lung cancer, primarily affecting workers in construction and shipbuilding.
• Benzene: Associated with leukemia and various blood cancers; commonly found in emissions from vehicles and industrial sources.
• Formaldehyde: Carcinogenic compound linked to nasopharyngeal cancer and leukemia; often found in building materials and household products.
• Vinyl Chloride: Causes liver cancer (specifically angiosarcoma of the liver); used in the production of PVC (polyvinyl chloride) plastics.
• Aflatoxins: Naturally occurring toxins produced by fungi, significantly linked to liver cancer through contaminated agricultural products.
• Polycyclic Aromatic Hydrocarbons (PAHs): Found in tobacco smoke, charred meats, and vehicle exhaust; linked to lung, skin, and bladder cancers.
• Arsenic: Associated with multiple cancer types including skin, lung, and bladder cancers, typically from contaminated drinking water.
• Cadmium: Heavy metal that increases the risk of lung cancer; exposure often occurs in industrial settings.
• Chromium VI: Recognized as a lung carcinogen, commonly encountered in occupational settings such as the manufacturing of steel.
• Nitrosamines: Present in tobacco products and processed meats; strongly linked to stomach and esophageal cancers.

Biological Carcinogens

• Human Papillomavirus (HPV): Major cause of cervical cancer, also linked to anal and oropharyngeal cancers.
• Hepatitis B and C viruses: Both viruses are significantly linked to liver cancer, notably in affected populations.
