There are three main types of lung cancer. Knowing which type you have is important because it affects your treatment options and your outlook (prognosis). If you aren’t sure which type of lung cancer you have, ask your doctor so you can get the right information.
Non-Small Cell Lung Cancer
This is the most common type of lung cancer. About 85% of lung cancers are non-small cell lung cancers. Squamous cell carcinoma, adenocarcinoma, and large cell carcinoma are all subtypes of non-small cell lung cancer.
Small Cell Lung Cancer
Small cell lung cancer is also called oat cell cancer. About 10%-15% of lung cancers are small cell lung cancers. This type of lung cancer tends to spread quickly.
Lung Carcinoid Tumor
Fewer than 5% of lung cancers are lung carcinoid tumors. They are also sometimes called lung neuroendocrine tumors. Most of these tumors grow slowly and rarely spread.
Lung Cancer Prevention and Screening
Tobacco use is the number one cause of lung cancer, but people who don’t smoke may get lung cancer too. Learn about the known causes of lung cancer, what you can do to lower your risk, and tests that may help find it early.
