Lung cancer continues to be the single biggest cancer killer. In 2006, an estimated 162,460 will die of lung cancer; more people than breast, prostate, colon, liver, melanoma, and kidney cancers combined. Few people are even aware that lung cancer kills
three times as many men as prostate cancer, and nearly twice as many women as breast cancer !!
Prostate cancer has a 99 percent 5-year survival rate and breast cancer has an 88 percent 5-year
survival rate. Over 50 percent of new lung cancer cases will be diagnosed at a very late stage;
Stage IIIb or IV. Lung cancer has a 5-year survival rate of only 15 percent.
That means that 85 percent of people who get lung cancer die within five years.!!!!!
About Lung Cancer
Lung Cancer is a disease that begins in the tissue of the lungs. The lungs are sponge-like organs that are part of the respiratory system. During breathing, air enters the mouth or nasal passage and travels down the trachea. The trachea splits into two sets of bronchial tubes that lead to the left and right lung.
The bronchi branch off into smaller and smaller tubes that eventually end in small balloon-like sacs known as alveoli. The alveoli are where oxygen, carbon dioxide, and other substances are exchanged between the lungs and the blood stream.
The vast majority of Lung Cancer cases fall into one of two different categories:
Non-Small Cell Lung Cancer is the most common type of Lung Cancer, making up nearly 80% of all cases. This type of Lung Cancer grows and spreads more slowly than small cell lung cancer.
Non-small cell lung cancer is divided into three different subcategories.
Squamous cell carcinoma originates in the thin, flat cells that line the passages of the respiratory tract.
Adenocarcinoma begins in the cells that form the lining of the lungs.
Large cell carcinomas make up a group of cancers that look large and abnormal under a microscope.
Small Cell Lung Cancer makes up nearly 20% of all Lung Cancer cases.
It is associated with cancer cells smaller in size than most other cancer cells.
These cells may be small, but they can rapidly reproduce to form large tumors.
Their size and quick rate of reproduction allows them to spread to the lymph nodes and to other organs of the body.
This type of Lung Cancer is almost always caused by smoking or second hand smoke.
When cells of the lung start growing rapidly in an uncontrolled manner, the condition is called lung cancer. Lung cancer can affect any part of the lung. Lung cancer is the leading cause of cancer deaths in both women and men in the United States, Canada, and China.
Two main types of lung cancer exist: small-cell lung cancer (SCLC, also called oat cell cancer) and non–small-cell lung cancer (NSCLC). Small-cell lung cancer accounts for approximately 20-25% of all cases of lung cancer.
Small-cell lung cancer differs from non–small-cell lung cancer in the following ways:
Small-cell lung cancer grows rapidly.
Small-cell lung cancer spreads quickly.
Small-cell lung cancer responds well to chemotherapy (using medications to kill cancer cells) and radiation therapy (using high-dose x-rays or other high-energy rays to kill cancer cells).
Small-cell lung cancer is frequently associated with distinct paraneoplastic syndromes (collection of symptoms that result from substances produced by the tumor, occurring far away from the tumor).
Another type of tumor, called carcinoid, can occur in the lung.
