Asbestos
ContaminantIARC Group 1Heat-resistant fibers built into ships, older buildings, brakes, and insulation.
Where it comes from in service
Navy ships and shipyards, engine and boiler rooms, demolition, and any work disturbing old insulation.
How it harms the body
Asbestos fibers lodge in lung tissue and the lung lining and can cause scarring (asbestosis), lung cancer, and mesothelioma — often decades after exposure.
How long it stays in you
Fibers can remain in the lung for life; disease latency is often 20–40 years.
Where it goes — tap an organ to go deeper
IARC lists asbestos as a known carcinogen; the VA recognizes asbestos-related disease (asbestosis, lung cancer, mesothelioma) claimed by exposure history.
Because latency is so long, a documented exposure history is essential even when you feel well today.
What to ask your clinician about
- •Periodic lung screening given asbestos history
- •Chest imaging and pulmonary function testing
Bring this to your clinician and your VSO — they decide what testing and care, if any, is right for you. For general, whole-person ways to support your body, see Whole health.
