Do genetic factors increase the risk of lung cancer? https://www.oncologistdrdodulmondal.com/lung-cancer-oncologist-delhi-ncr-india/ Yes, genetic factors can increase the risk of lung cancer, even in non-smokers. Inherited gene mutations and family history may make individuals more vulnerable to abnormal cell growth in the lungs. Certain genetic changes can also affect how the body responds to carcinogens like tobacco smoke or air pollution. While lifestyle factors remain the leading cause, genetics can significantly influence susceptibility, making early screening and awareness important.
