Question

what is mesothelioma, and how is it primarily caused?

a type of skin cancer caused by sun exposure

a bacterial infection that occurs in the lungs caused by pollution

a type of cancer affecting the abdominal lining or pleural cavity, primarily caused by asbestos exposure

a type of cancer that occurs due to viral infections

Explanation:

Identify the definition of mesothelioma

Mesothelioma is a rare and aggressive form of cancer that develops in the thin layer of tissue (mesothelium) covering the lungs, abdomen, heart, and other internal organs.

Determine the primary cause

The primary risk factor and cause of mesothelioma is exposure to asbestos fibers. When asbestos fibers are inhaled or swallowed, they can become permanently trapped in the protective linings of the lungs (pleura) or abdomen (peritoneum), leading to chronic inflammation and cellular damage over time.

Match with the correct option

The third option correctly defines mesothelioma as a type of cancer affecting the abdominal lining or pleural cavity, primarily caused by asbestos exposure.

Answer:

• (A) A type of skin cancer caused by sun exposure
• (B) A bacterial infection that occurs in the lungs caused by pollution
• (C) A type of cancer affecting the abdominal lining or pleural cavity, primarily caused by asbestos exposure (Correct answer)
• (D) A type of cancer that occurs due to viral infections
