Question

Answer

Introduction:
This question pertains to the correlation between cigarette smoking and exposure to benzene, a known carcinogen. The statements provided are:
1. Cigarette smoking exposes a person to benzene.
2. Benzene is a known carcinogen.

Explanation:
Statement 1: Cigarette smoking exposes a person to benzene.
Cigarette smoke is a complex mixture of over 7,000 chemicals, including numerous toxic and carcinogenic substances. Benzene is one such chemical present in cigarette smoke. When a person smokes a cigarette, the burning process releases benzene, which is then inhaled into the lungs and absorbed into the bloodstream. Therefore, statement 1 is correct.

Statement 2: Benzene is a known carcinogen.
Benzene is indeed a known carcinogen, which means it has the potential to cause cancer in humans. Prolonged exposure to benzene has been linked to various types of cancer, including leukemia (cancer of the blood cells), as well as cancers of the bone marrow, lymphatic system, and other organs. It is classified as a Group 1 carcinogen by the International Agency for Research on Cancer (IARC), indicating that there is sufficient evidence to establish its carcinogenicity in humans. Therefore, statement 2 is correct.

Conclusion:
Both statements 1 and 2 are correct. Cigarette smoking exposes individuals to benzene, which is a known carcinogen. This highlights one of the many harmful effects of smoking and reinforces the importance of tobacco control measures to protect public health.
