2. Non Small cell lung cancer or NSCLC

Small cell lung cancer or SCLC is rare one. Out of every 100-lung cancer patients, 20 are diagnosed with this type of cancer.
This type of cancer is named so because the cancer cells are small and filled up with nucleus. But it grows very fast This type of cancer also know as oat cell lungs cancer.
Smoking is the main reason of this cancer. It is very rare in case of nonsmokers.

2. Adenocarcinoma
3. Large cell carcinoma

Squamous cell cancer is most common type of lung cancer. It commonly develops in inner lining of both bronchi.

Adenocarinoma develops from the cell, which produces mucus known as phlegm. Normal occurance of this type of cancer is outer region of lungs.

Large cell carcinoma is named so because they look as large cell under microscope.
The Non small cell lung cancer or NSCLC generally develops in both smokers and passive smokers.
