It is usually resulting from exposure to asbestos.
In 2021, only about 2,800 of the 209,500 cases of lung cancer in the U.S. were mesothelioma.
This applies to even the most common types of the disease.

Genes play a key role, especially in younger people with the disease.
There seems to be a link between genes and lung cancer in nonsmokers as well.
Identifying gene mutations has paved the way for targeted lung cancer testing and therapies.
If you’ve never smoked, you may still want to ask your healthcare provider about screening.
While many factors influence why a person gets lung cancer, smoking remains the top cause.
A person’s sex assigned at birth, age, and genetics also influence their risk of lung cancer.
