What term describes a carcinogen?

• A. A substance that can cause inflammatory reactions
• B. A substance that does not affect cells
• C. A substance that causes mutations
• D. A substance capable of causing cancer in living tissue

Answer: (D)

A carcinogen is any substance capable of causing cancer in living tissue. In HazMat thinking, this means exposure to such agents can lead to cancer after sufficient contact, whether the agent damages DNA directly or promotes abnormal cell growth through other mechanisms. The other descriptions miss the defining idea: inflammatory reactions can occur with exposure but aren’t the cancer-causing property by definition; something that doesn’t affect cells isn’t a carcinogen; a substance that causes mutations describes mutagens, which is related but not the exact term for cancer-causing agents. Hence, the term that best fits is the one that directly states it can cause cancer in living tissue.
