What is the definition of "carcinogen"?

• A. A substance that can cause respiratory issues
• B. A chemical that can lead to skin irritation
• C. A substance capable of causing cancer in living tissue
• D. A compound that enhances metabolic rates

Answer: (C)

A carcinogen is defined as a substance capable of causing cancer in living tissue. This definition highlights its specific role in cancer development, distinguishing it from other types of hazardous materials. Carcinogens can initiate or promote cellular changes that lead to uncontrolled cell growth, a hallmark of cancer. Understanding this definition is crucial for anyone studying toxicological hazards because it emphasizes the importance of identifying and managing exposure to potential carcinogenic substances in various environments, including workplaces, laboratories, and consumer products. The other options refer to different health concerns: respiratory issues and skin irritation are reactions to allergens or irritants but do not specifically indicate a cancer risk, while a compound enhancing metabolic rates does not imply any cancer-causing potential. Focusing on the definition of carcinogens helps clarify their unique impact on human health compared to other types of hazardous substances.
