Solution
Lung cancer is mainly caused due to cigarette smoking.
Explanation:
Cigarette smoking is the primary cause of lung cancer, leading to uncontrolled growth of malignant cells in lung tissues. Tobacco smoke contains numerous carcinogens such as polycyclic hydrocarbons and radioactive substances, which induce DNA damage in the respiratory tract lining, promoting cancer development. Smoking also increases the risk of cancers of the larynx, esophagus, bladder, and other organs, but lung cancer is the most common and deadly among them.
