What is non-small cell lung cancer?

American Cancer Society answered:About 85% to 90% of lung cancers are non-small cell lung cancer (NSCLC). About 10% to 15% are small cell lung cancer (SCLC), named for the size of the cancer cells when seen under a microscope.
There are 3 main subtypes of NSCLC.
- Squamous cell (epidermoid) carcinoma
- Adenocarcinoma
- Large cell (undifferentiated) carcinoma
The cells in these subtypes differ in size, shape, and chemical make-up when looked at under a microscope. But they are grouped together because the approach to treatment and prognosis (outlook) are very similar.

Non-small cell lung cancer is the most common type of lung cancer, in which malignant tumors start growing in your lungs. As many as 87 percent of lung cancers are non-small cell carcinomas. Adenocarcinoma, squamous cell carcinoma, and large cell carcinoma are all types of non-small cell lung cancer.

Johns Hopkins Medicine answered:Non-small cell lung cancer is the most common type of lung cancer, accounting for 75-85 percent of cases. Non-small cell lung cancer includes:
- squamous cell carcinoma - often begins in the bronchi near the middle of the lungs.
- adenocarcinoma - begins along the outer edges of the lungs and under the lining of the bronchi. It is the most common type of lung cancer in people who have never smoked.
- large cell carcinoma - group of cancers with large, abnormal-looking cells. These tumors may begin anywhere in the lungs.
- undifferentiated carcinomas - cells that lack any of the defined characteristics of other carcinomas.

Dr. Steven Scott of Riverside Heart and Vascular Center answered:Primary cancers of the lung are generally divided into two groups: non-small cell lung cancer and small cell lung cancer. The term “primary” means that the cancer originated from the cells in the lung rather than spreading to the lung from another organ. Non-small cell lung cancer is the more common type, making up about 85% of all primary lung cancers. Non-small cell lung cancer tends to grow and spread more slowly than small cell lung cancer, and it is treated with surgery if detected at an early stage. Small cell lung cancer tends to spread more rapidly, and it is usually treated with chemotherapy rather than surgery.

Non-small cell lung cancer is the most common type of lung cancer. It often grows and spreads less rapidly than small cell lung cancer. There are three types of non-small cell lung cancer -- squamous cell carcinoma, adenocarcinoma and large cell carcinoma.
Lung cancer usually begins in one lung. If left untreated, it can spread to lymph nodes or other parts of the chest, including the other lung. Lung cancer can also spread throughout the body to the bones, brain, liver or other organs.Non-small cell lung cancer is the most common type of lung cancer.
