Can you be tested for lung cancer gene?

A person with lung cancer undergoes genetic testing so that their doctor can identify certain mutations in genes linked with cancer. Then, the doctor may be able to recommend a treatment that targets the specific mutation but leaves healthy cells intact.

How likely is it to inherit cancer?

It’s estimated that between 3 and 10 in every 100 cancers are associated with an inherited faulty gene.
