Mesothelioma is a rare cancer that develops in the mesothelium, the protective lining covering the lungs, abdomen, and heart.
Question 2: What is the primary known cause of mesothelioma?
- Smoking tobacco
- Asbestos exposure (Correct answer)
- Radiation therapy
- Chemical solvents
Correct answer: Asbestos exposure
Asbestos fiber inhalation or ingestion is the primary and well-established cause of mesothelioma in virtually all diagnosed cases.
Question 3: How long is the typical latency period between asbestos exposure and mesothelioma diagnosis?
- 1–5 years
- 5–10 years
- 20–50 years (Correct answer)
- 10–15 years
Correct answer: 20–50 years
Mesothelioma has an exceptionally long latency period of 20–50 years, meaning symptoms often don't appear until decades after initial asbestos exposure.
Question 4: Which form of mesothelioma is the most common?
- Peritoneal mesothelioma
- Pericardial mesothelioma

Pleural mesothelioma, which affects the lining of the lungs, accounts for approximately 75–80% of all mesothelioma diagnoses.
Question 5: Which diagnostic test is most commonly used to confirm a mesothelioma diagnosis?
- MRI scan
- Blood test
- Tissue biopsy (Correct answer)
- Chest X-ray
Correct answer: Tissue biopsy
A tissue biopsy is the definitive method to confirm mesothelioma, as it allows pathologists to examine cancer cells under a microscope.

- Severe headaches
- Shortness of breath and chest pain (Correct answer)
- Abdominal swelling
- Joint pain
Correct answer: Shortness of breath and chest pain
