Non small cell lung cancer

Non-small cell lung cancer is the most common type of lung cancer. It usually grows and spreads more slowly than small cell lung cancer. There are three common forms of non small cell lung cancer: Adenocarcinomas are often found in an outer area of the lung. Squamous cell carcinomas are usually found in the center of the lung next to an air tube (bronchus). Large cell carcinomas can occur in any part of the lung. They tend to grow and spread faster than the other two types.
