How can genetic changes result in lung cancer?

ANSWER

Sometimes, changes to the DNA of your lung cells, known as mutations, can lead to cancer. There are several ways this can happen.

For example, you may be born with problems in chromosome number 6 that make you more likely to get lung cancer. Or, you may naturally have less of an ability to clear away chemicals from your body that can cause the disease.

Another possibility is that your body may be unable to repair damaged DNA, which puts you at higher risk when you come into contact with chemicals that can cause lung cancer.
