What term describes cancer-causing molecules?

• A. Toxins
• B. Carcinogens
• C. Mutagens
• D. Pathogens

Answer: (B)

Carcinogens are substances that cause cancer by damaging DNA or promoting uncontrolled cell growth. They include chemicals, radiation, and certain viruses that disrupt how cells regulate division. The connection to cancer comes from their ability to induce genetic changes or create environments where cells multiply abnormally, eventually forming tumors. While mutagens cause DNA mutations and can contribute to cancer, mutagens are a broader category and not defined specifically as cancer-causing. Toxins are general poisons, not necessarily linked to cancer, and pathogens are disease-causing organisms; some pathogens are associated with cancer, but the precise term for cancer-causing molecules is carcinogens.
