5 Facts About Non-Small Cell Lung Cancer
There are two major forms of lung cancer that can be differentiated on the basis of the structural (morphological) appearance of the cancer cells under a microscope. These two major types of lung cancer are non-small cell lung cancer and small cell lung cancer. Here are some facts about non-small cell lung cancer (NSCLC).
- Squamous cell (epidermoid) carcinoma - accounts for about one-third of NSCLC cases and usually occurs in smokers.
- Adenocarcinoma - accounts for about 35 percent of NSCLC cases and can occur in both smokers and non-smokers.
- Large cell carcinoma - this is a very aggressive form of NSCLC that grows and spreads rapidly. It accounts for less than 10 percent of NSCLC cases.
