Why is asbestos often referred to as a "silent killer"?

Asbestos is commonly referred to as a "silent killer" because it can take years, often decades, for symptoms of asbestos-related illnesses to manifest after exposure. Many individuals may not realize they have been exposed to asbestos until symptoms arise, which often occur long after the initial exposure. This delayed onset of disease, such as asbestosis, lung cancer, or mesothelioma, means that individuals may lead a normal life without knowledge of the underlying harm being done to their lungs and respiratory systems.

The implications of this delayed symptom presentation highlight the importance of awareness and education regarding the dangers of asbestos exposure, as individuals may unknowingly carry risks for serious health issues for many years following initial contact. This characteristic of asbestos contributes significantly to the urgency for proper handling and regulations concerning its presence in buildings and materials.
