Asbestosis & Lung Cancer

Whenever I passed buy a clinic on the specialist of Asbestosis & Lung Cancer, I always asked myself what is meant by asbestosis and how are they related to lung cancer. I think asbestosis is an ailment cause by asbestos. I checked out for its meaning and then found out that it is a noncombustible grayish mineral that occurs in fibrous form and has been used as a fireproof material.
