Lung Cancer Home > Non-Small Cell Lung Carcinoma

Lung cancer is a condition in which the growth of malignant (cancerous) cells begins in the tissues of the lung. There are two main types: small cell lung cancer and non-small lung cancer.  
Non-small cell lung cancer has many subtypes, such as:
  • Squamous cell carcinoma: Cancer that begins in squamous cells, which are thin, flat cells that look like fish scales. This is also called epidermoid carcinoma.
  • Adenocarcinoma: Cancer that begins in cells that have glandular (secretory) properties.
  • Large cell carcinoma: Cancer in which the cells are large and look abnormal when viewed under a microscope.
Compared to small cell lung cancer, non-small cell lung cancer grows and spreads more slowly. This type of lung cancer is also much more common.
