Nonsmall cell lung cancer is more widespread than small cell lung cancer, and generally it grows and spreads more gradually. The remaining lung cancers are all non-small cell (NSCLC).
There are three sub-types of NSCLC. The cells in these sub-types fluctuate in size, shape, and chemical make-up.
Squamous cell carcinoma: About 25% - 30% of all lung cancers are Squamous cell carcinomas. They are linked with a history of smoking and tend to be found centrally, near a bronchus.
Squamous cell carcinoma generally starts in the bronchi and doesn’t usually spread as rapidly as do other lung cancers
Adenocarcinoma: This type of cancer accounts for about 40% of lung cancers and is typically found in the outer region of the lung. Adenocarcinoma is more commonly found in women than in men.
Large-cell undifferentiated carcinoma: This kind of cancer accounts for about 10% - 15% of reported lung cancers. It appears in any part of the lung and tends to grow and spread quickly throughout the body ensuing in a poor prediction of recovery.
Large cell carcinoma is any lung tumor that cannot be classified
