Types of Lung Cancer

The four major types of lung cancer are
1) Small Cell or Oat Cell Carcinoma
2) Squamous Cell Carcinoma
3) Adenocarcinoma (includes a subtype known as bronchioalveolar)
4) Large cell carcinoma.

Squamous carcinoma, adenocarcinoma, and large cell carcinoma are categorized as non-small cell lung cancers.  Non-small cell lung cancers are the most common form of lung cancer, accounting for over 80% of all lung cancers today. 

Determining what type of tumor you have is a critical step for your doctors.  Your tumor type determines what form of treatment will be administered.
