What is the latency period for mesothelioma?

• A. 5-10 years
• B. 15-50 years
• C. 60-70 years
• D. 1-5 years

Answer: (B)

Latency after asbestos exposure is measured in decades, because the cancer develops from long-term fiber exposure that gradually causes cellular changes and chronic inflammation. Most mesotheliomas appear after about 15 to 50 years, though individual factors like exposure intensity, duration, and biology can shift this range. Onsets earlier than about 10 years are uncommon, and while very late cases (60–70 years) can occur, they are less typical. Therefore, 15–50 years best captures the common range.
