Mesothelioma is most commonly associated with exposure to which of the following?

• A. Fiberglass
• B. Asbestos
• C. Silica
• D. Pollution

Answer: (B)

Mesothelioma is most commonly associated with exposure to asbestos due to the unique properties of this mineral that promote its inhalation and retention within the lungs. Asbestos fibers can become airborne and, when inhaled, can settle in the pleura, the tissue lining the lungs. Over time, these fibers can cause damage to the cells in this lining, leading to inflammation, cellular changes, and, ultimately, malignant transformation. This connection between asbestos exposure and the development of mesothelioma has been well-established through numerous studies, making asbestos the primary risk factor for this aggressive form of cancer.

Other substances listed, such as fiberglass, silica, and pollution, can lead to various respiratory diseases and conditions, but they do not have the same strong, causal link with mesothelioma as asbestos does. While fiberglass can irritate lung tissue, it does not carry the same risk for developing mesothelioma. Silica exposure is associated with silicosis and other lung diseases, but again, not specifically with mesothelioma. Pollution in general can contribute to a variety of health issues, but it is not a direct cause of mesothelioma in the same manner that asbestos is. Thus, the connection between asbestos and mesothelioma is pivotal in understanding the disease
