Approximately 85% of all instances of lung cancer are classified as non-small-cell lung cancer (NSCLC). The reason it is called "non-small-cell" lung cancer is that, when examined under a microscope, the cancer cells are bigger than small-cell lung cancer cells.

The most prevalent subtypes of non-small cell lung cancer (NSCLC) include adenocarcinoma, squamous cell carcinoma, and giant cell carcinoma. Important Information about Non-Small Cell Lung Cancer1.

NSCLC Types:Adenocarcinoma: This subtype is more common in non-smokers and ex-smokers and frequently starts in the outer regions of the lungs. Squamous Cell Carcinoma: This type of cancer is usually located in the lungs' central airways and is highly correlated with a history of smoking.

Less frequently occurring, large cell carcinoma can develop anywhere in the lung. It usually spreads and grows swiftly.

2. Reasons and Danger Factors:NSCLC is primarily caused by smoking, although nonsmokers can also get this kind of lung cancer.

A family history of lung cancer, exposure to secondhand smoke, and environmental contaminants like radon and asbestos are other risk factors. .
