2 Am I at risk?
Family who’ve had lung cancer
If a close blood relative has had lung cancer, your risk for lung cancer is higher
than a person with no family history. Your risk is even higher if your relative had
cancer at a young age or if multiple relatives have had lung cancer. Lung cancer
in families may be due to a shared environment, genes, or both.
History of lung disease
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.
Second-hand smoke
In 1981, a link between second-hand smoke and lung cancer was first
suggested. Since then, many studies have found that second-hand smoke can
cause lung cancer in people who don’t smoke. The more contact you have with
second-hand smoke, the higher your risk for lung cancer.
