Are You at Risk for Lung Cancer?

Types Of Lung Cancer

There are two main types of lung cancer: non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC).

Non-Small Cell Lung Cancer

This is the most common type of lung cancer, accounting for 85 percent to 90 percent of lung cancers. There are several types of NSCLC.

  • Squamous cell carcinoma begins in squamous cells, which are thin, flat cells that look like fish scales. This is also called epidermoid carcinoma.

  • Large cell carcinoma may begin in several types of large cells.

  • Adenocarcinoma begins in the cells that line the alveoli and make substances such as mucus.

  • Bronchiolo-alveolar carcinoma is a less aggressive subtype of adenocarcinoma.

Small Cell Lung Cancer

SCLC is a disease in which malignant (cancerous) cells form in lung tissue. It usually is an aggressive cancer, with two-thirds of patients having the disease spread to another part of the body at the time of diagnosis. There are several types of SCLC:

  • Small cell carcinoma (oat cell cancer)

  • Mixed small cell/large cell carcinoma

  • Combined small cell carcinoma
