Lung Cancer

What is lung cancer?How is is caused?

Basically it is the uncontrollable growth of abnormal cells in one or both lungs. Like any other cancer it can be accrued genetically, but smoking is also a leading cause of cancer.
IT is strange that people are inhaling their own death by choice. It i has been proven by doctors that lung cancer holds the largest of its population in the cancer family.

Types and staging:

There are two types of lung cancer:

Non-small cell lung cancer:

Stage I: The cancer is located only in the lungs and has not spread to any lymph nodes.

Stage II: The cancer is in the lung and nearby lymph nodes.

Stage III: Cancer is found in the lung and in the lymph nodes in the middle of the chest, also described as locally advanced disease. Stage III has two subtypes:

Stage IV: This is the most advanced stage of lung cancer, and is also described as advanced disease. This is when the cancer has spread to both lungs, to fluid in the area around the lungs, or to another part of the body, such as the liver or other organs.

Small cell lung cancer:

Limited stage: In this stage, cancer is found on one side of the chest, involving just one part of the lung and nearby lymph nodes.

Extensive stage: In this stage, cancer has spread to other regions of the chest or other parts of the body.

More recently, the American Joint Commission on Cancer implemented a more detailed staging system in which the stages of small cell lung cancer are described using Roman numerals and letters (for example, Stage IIA). This is the same method that is used for non-small cell lung cancer in describing the growth and spread of the cancer.
