Types of Lung Cancer
Lung cancer is designated by two types:
- Small Cell Lung Cancer (SCLC)
- Non-Small Cell Lung Cancer (NSCLC)
Both small cell lung cancer and non-small cell lung cancer are named for the kinds of cells found in the cancer and how the cells appear when viewed under a microscope. The cancer cells of each type grow and spread in different ways.
The two general types of small cell lung cancer include:
- Small cell carcinoma (oat cell cancer)
- Combined small cell carcinoma
Smoking tobacco is the major risk factor for developing small cell lung cancer.
Each year in the United States, more than 226,000 people are diagnosed with non-small cell lung cancer. There are several different types of this cancer.
The three main types of non-small cell lung cancer include:
- Squamous cell carcinoma (epidermoid carcinoma)
- Large cell carcinoma
Other less common types of non-small cell lung cancer are: pleomorphic, carcinoid tumor, salivary gland carcinoma, and unclassified carcinoma.
Smoking can increase the risk of developing non-small cell lung cancer.
