Asbestos Contractor/Supervisor Practice Exam 2026 - Complete Prep Guide

The primary health risk associated with asbestos exposure is indeed cancer, particularly lung cancer and mesothelioma, which is a rare but aggressive cancer affecting the linings of the lungs, abdomen, or heart. Asbestos fibers, when inhaled, can become trapped in lung tissues, leading to inflammation, scarring, and ultimately cellular changes that may result in cancerous growths over time. The latency period for these diseases can be decades, meaning symptoms may not appear until many years after exposure, which underscores the serious nature of asbestos-related health risks.

In contrast, other options such as skin irritation, respiratory issues, and allergic reactions, while they may occur to varying degrees in some cases of asbestos exposure, do not reflect the primary and most severe long-term health consequences associated with this substance. Skin irritation is generally not a common issue connected to asbestos fibers, and while short-term exposure might cause mild respiratory issues, the most significant danger lies in the potential for cancer development.
