Lung Cancer Types : Non-small Cell Lung Cancer, Small Cell Lung Cancer

FOR IMMEDIATE RELEASE
(Free-Press-Release.com) December 27, 2004 -- The two main types of lung cancer are non-small cell (80% of all cases) and small cell (20% of all cases). The names refer to the kinds of cells that make up the tumor rather than the size of the tumor.

===============================

Non-small Cell Lung Cancer

Non-small cell lung cancer is classified into three subtypes:



1. Adenocarcinomas

found in the mucus glands





2. Squamous or epidermoid carcinoma

located in the bronchial tubes

3. Large cell carcinoma

found near the surface

Lung cancer almost always begins in one lung and, if left untreated, can spread to lymph nodes or other tissues in the chest (including the other lung). Lung cancer can also metastasize (or spread) throughout the body, to the bones, brain, liver, or other organs.

===============================

Small Cell Lung Cancer

Small cell lung cancer is highly associated with smoking and grows and
spreads quickly. There are two stages of the disease: limited and

extensive.
