Besides radon, there are 10 other agents known to cause lung cancer. Five are
metallic metals: arsenic, beryllium, cadmium, chromium, and nickel. The others
are asbestos, coal smoke, soot, silica, and diesel fumes. Among people who’ve
had contact with these agents, the risk for lung cancer is higher for those who’ve
smoked than for those who’ve never smoked.
Infectious diseases
Some infectious diseases have been linked to lung cancer. Tuberculosis is an
infection caused by bacteria. If you’ve had tuberculosis, you are more likely to
get lung cancer than someone who’s never had tuberculosis. The same is true
if you’ve had a fungal infection in the lungs.
Other lung diseases
Two lung diseases have been linked to lung cancer. A history of COPD (
c
hronic
o
bstructive
p
ulmonary
d
isease) increases your risk for lung cancer. COPD
makes breathing hard because the lung tissue is damaged or there’s too
much mucus. The second disease linked to lung cancer is pulmonary fibrosis.
Pulmonary fibrosis is major scarring of lung tissue that makes it hard to breathe.
