Lung Cancer Risk Factors Common risk factors are
- Use of tobacco in any form - Cigarettes, Cigar and Pipe smoking
- Exposure to substances such as arsenic, radon and asbestos, as part of occupation
- Exposure to second-hand smoke (passive smoking)
- Exposure to air pollution and environmental smoke
Lung Cancer SymptomsIn the early stages, there may be no symptoms. Later the signs that may appear include
- Persistent chough that does not respond to treatment
- Change in voice quality / hoarseness that persist
- Shortness of breath
- Sputum (spit) streaked with blood
- Chest pain
- Recurring Pneumonia or Bronchitis
Lung Cancer Early DetectionThere is currently no way to detect lung cancer early. These tests can, to an extent, help diagnose the disease
- Periodic Chest X-rays, analysis of cells in sputum and examination of the bronchia
- Newer tests, such as the low-dose spiral CT scan, may soon help detect early lung
Lung Cancer PreventionLung cancer remains a highly preventable disease because 90% of lung cancers occur in smokers or former smokers. The best way to prevent lung cancer is to not smoke. Also, included in the prevention methods are:
- Avoid tobacco in any form
- Quit smoking if you are a smoker
- Minimize exposure to passive smoking
- Create a smoke-free environment in your community
Lung Cancer TreatmentOnce diagnosed, treatment is determined by the type of lung cancer: either small cell or non-small cell. Depending on the type, following treatment options are available.
- Surgery - May involve removing the affected lobe of lung (lobectomy), or removing the entire lung (pneumonectomy)
- Radiation and Chemotherapy - Sometimes used in combination with surgery for later stages
