What Is Small Cell Lung Cancer?
Lung cancer is a disease in which the growth of malignant (cancerous) cells begins in the tissues of the lung. It is by far the leading cause of cancer death in the United States.
- 100,099 men and 80,163 women were diagnosed with lung cancer
- 90,121 men and 67,509 women died from lung cancer.
There are two general
types of lung cancer: small cell lung cancer and
non-small cell lung cancer. Small cell lung cancer is less common than the non-small cell lung cancer. Also, small cell lung cancer spreads more quickly than non-small cell lung cancer.
The lungs are a pair of cone-shaped breathing organs that are found within the chest. They bring oxygen into the body when breathing in and take out carbon dioxide when breathing out.
Each lung has sections called lobes. The left lung has two lobes. The right lung, which is slightly larger, has three. A thin membrane called the pleura surrounds the lungs.
Two tubes called bronchi lead from the trachea (windpipe) to the right and left lungs. The bronchi are sometimes also involved in lung cancer. Small tubes called bronchioles and tiny air sacs called alveoli make up the inside of the lungs.
