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.
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 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.
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.
Whether you’re worried about developing lung cancer, making decisions about treatment, or trying to stay well after treatment, we can help.
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.
If you are facing lung cancer, we can help you learn about your treatment options and possible side effects, and point you to information and services to help you get through treatment and live well afterward.
The American Cancer Society is committed to relentlessly pursuing the answers that will save lives from lung cancer. In fact, the Society has been a part of nearly every major cancer research breakthrough in recent history.
