Which statement about carcinogens is true?

• A. Carcinogens increase cancer risk.
• B. Carcinogens always cause immediate death.
• C. Carcinogens only affect the skin.
• D. Carcinogens are the same as irritants.

Answer: (A)

Carcinogens are substances or exposures that increase the probability of developing cancer, rather than guaranteeing it or causing immediate death. They can damage DNA or disrupt how cells regulate growth, and cancer risk typically accumulates with higher dose and longer exposure, often after a long latency. Effects can involve many tissues, not just the skin, and the outcome depends on factors like exposure route, duration, and individual susceptibility. They are not the same as irritants, which mainly cause inflammation or acute damage without necessarily increasing cancer risk. In short, carcinogens raise the likelihood of cancer, rather than causing immediate death or limited tissue effects.
