Lung Cancer; A Disease That Traps Both Smokers And Non-Smokers

The Three Types

The American Cancer Society (ACS) states “non-small cell lung cancer (NSCLC) accounts for about 80 percent of lung cancer cases. The three main subtypes of NSCLC are:

-Adenocarcinoma. This accounts for 40 percent of lung cancer cases. It is usually found in the outer parts of the lung. It tends to grow slower than the other two subtypes, so there is a better chance of a tumor being found before it has spread.

-Squamous cell carcinoma. This accounts for about 25-30 percent of lung cancers. It grows from the cells that line the insides of the lung’s airways. Squamous cell carcinoma is usually found at the center of the lung.

-Large cell carcinoma. This accounts for 10-15 percent of lung cancers. It can be found in any part of the lung, and tends to grow faster than the other subtypes.”
