Dr. Abraham Chachoua, the Jay and Isabel Fine Professor of Oncology at NYU Langone Medical Center's Laura and Isaac Perlmutter Cancer Center, explains the different causes of lung cancer.
He explains that in the world of lung cancer, the cigarette can play an important role in causing cancer due to its carcinogenic chemicals. The chemicals in cigarette smoke can alter DNA, lung lining, and how you breathe. The process of carcinogenesis occurs, which is where a normal cell transforms to a malignant cell. So if you imagine that you are inhaling into your lung these carcinogens, at some point something is going to change in the lung that could possibly lead to the development of cancer.
There are other factors that can cause lung cancer besides just smoking. For example, exposure to secondhand smoke, radon, asbestos, and in some cases, environmental pollutants may also lead to the development of lung cancer.
