THE LUNGS

THE LUNGS

THE LUNGS
Your lungs are two sponge-like organs located in your chest. The left lung is smaller to allow room for the heart (American Cancer Society, 2013).

Cancers in the lungs begin in the cells lining, the bronchi, and in other parts of the lung, such as the bronchioles or alveoli. In addition, lung cancers start as areas of pre-cancerous changes to the lung (American Cancer Society, 2013).
MAJOR TYPES OF LUNG CANCERS
There are two major types of lung cancers, small cell lung cancer and non-small cell lung cancer. Thus, these two types of lung cancers are treated completely differently (American Cancer Society, 2013).
WHAT IS SMALL CELL LUNG CANCER?
Small cell lung cancer (SCLC) usually begins in the bronchi near the center of the chest, and it tends to grow and spread quickly. Approximately 10% to 15% of all lung cancers are SCLC, which are named for the size of the cancer cells when seen under a microscope. More important, it usually spreads to other parts of the body before it is found (American Cancer Society, 2013).

When cells from the cancer break away from the original tumor and spread to other parts of the body it is known as “metastasize” (American Cancer Society, 2013). Furthermore, the lymph system is one way in which lung cancers are spread, and the lymph system has several parts to allow the cancer to travel (American Cancer Society, 2013).
