Lung Cancer is divided into two major types, non-small cell lung cancer - more common and generally grows and spreads more slowly, and small cell lung cancer (sometimes called oat cell) - grows more quickly and is more likely to spread to other organs in the body.

What everyone should know about lung cancer:

• Lung cancer is the second most common cancer among men and women and the leading cause of cancer death in both sexes.
  
  
• Lung cancer is the leading cause of death in African-Americans.
  
  
• Cigarette smoking accounts for nearly 90% of all lung cancers.

Risk Factors

• Tobacco Use - Harmful substances, called carcinogens, in tobacco damage the cells in the lungs. Persons who smoke cigarettes, cigars and pipes have a higher risk of lung cancer than nonsmokers.
  
  
• Lung Diseases - Certain lung diseases, such as tuberculosis (TB), increase a person's chance of developing lung cancer.
  
  
• Personal History - A person who has had lung cancer once is more likely to develop a second lung cancer compared with a person who has never had lung cancer.
  
  
• Exposure to:
  
  • Environmental Tobacco Smoke - The chance of developing lung cancer is increased by exposure to secondhand smoke.
  • Radon - Radioactive particles found in mines and it may be found in some houses. Damages the cells lining the lung. Long-term exposure can lead to lung cancer.
  • Asbestos - Asbestos is the name of a group of minerals that occur naturally as fibers and are used in certain industries.
    
    
• Pollution - Researchers have found a link between lung cancer and exposure to certain air pollutants, such as by-products of the combustion of diesel and other fossil fuels.

Signs and Symptoms:
Common signs and symptoms of lung cancer include:

• A cough that doesn't go away and gets worse over time
• Constant chest pain
• Coughing up blood
• Shortness of breath, wheezing, or hoarseness
• Repeated problems with pneumonia or bronchitis
• Swelling of the neck and face
• Loss of appetite
• Weight loss
  
• Fatigue

These symptoms may be caused by lung cancer or by other conditions. It is important to check with a doctor.

Guidelines for Diagnosing Lung Cancer

Doctors evaluate a person's medical history, smoking history, exposure to environmental and occupational substances, and family history of cancer. The doctor also performs a physical exam and may order a chest x-ray and other tests. If lung cancer is suspected, sputum cytology (the microscopic examination of cells obtained from a deep-cough sample of mucus in the lungs) is a simple test that may be useful in detecting lung cancer. For confirmation, a biopsy is performed--removal of a small sample of tissue for examination under a microscope by a pathologist-which can show whether a person has cancer.
