Types of Lung Cancer
Asbestos Lung Cancer
Asbestos exposure causes lung
cancer. Asbestos is the name of a group of minerals that
occur naturally as fibers and are used in certain industries.
Asbestos fibers tend to break easily into particles that can
float in the air and stick to clothes where they can expose others in the home. When clothing that has asbestos is washed, the fibers and dust can be inhaled by the person washing the clothes, or others nearby. When the particles
are inhaled, they can lodge in the lungs, damaging cells and
increasing the risk for lung cancer.
Studies have shown that
workers who have been exposed to large amounts of asbestos
have a risk of developing lung cancer that is 3 to 4 times
greater than that for workers who have not been exposed to
asbestos. This asbestos exposure
has been observed in such industries as shipbuilding, asbestos
mining, manufacturing, insulation work, and brake repair.
Asbestos and Other Carcinogens
People who have been exposed to asbestos and are also exposed
to other carcinogens, such as those in cigarette
smoke, have a significantly greater risk of developing
lung cancer than people who have only been exposed to asbestos alone.
One study indicates that asbestos
workers who smoke are about 90 times more likely to develop
lung cancer than people who neither smoke nor have been exposed
