About Lung Cancer
Types of Lung Cancer
There are two major types of lung cancer, Non-small cell and small cell lung cancer.
-
Non-small cell carcinoma (NSCLC) accounts to 85-90% of lung cancers. There are three subtypes of NSCLC depending on how the cells look under the microscope. The three subtypes are:
-
squamous cell carcinoma
-
adenocarcinoma
-
large cell carcinoma.
-
-
Small cell carcinoma accounts for 10-15% of all lung cancers. This type of cancer is almost always caused by smoking. It is very rare for someone who has never smoked to develop it.
