What are the Causes?
The primary causes of lung cancer include:
- Smoking: The leading cause of lung cancer, responsible for approximately 85% of cases. This includes both direct smoking and exposure to secondhand smoke.
- Radon Exposure: Radon is a naturally occurring radioactive gas that can accumulate in homes, especially in basements. Long-term exposure increases the risk of lung cancer.
- Asbestos Exposure: Occupational exposure to asbestos can increase lung cancer risk, particularly in individuals who smoke.
- Air Pollution: Long-term exposure to air pollutants, including fine particulate matter, may increase the risk.
- Family History: A family history of lung cancer can increase the risk, suggesting a genetic predisposition.
- Other Chemicals: Exposure to certain industrial chemicals (such as arsenic, diesel exhaust, and some forms of radiation) can contribute to the risk.
What are the Symptoms?
Lung cancer symptoms can vary but commonly include:
- Persistent Cough: A cough that doesn't go away or worsens over time.
- Chest Pain: Pain that is often worsened by deep breathing, coughing, or laughing.
- Shortness of Breath: This can occur even during routine activities.
- Wheezing: A high-pitched whistling sound while breathing.
- Coughing Up Blood: This can range from small amounts to larger quantities.
- Weight Loss: Unexplained weight loss and loss of appetite.
- Fatigue: Feeling unusually tired or weak.
- Recurring Infections: Frequent respiratory infections such as bronchitis or pneumonia.
Early detection and treatment of lung cancer can significantly improve outcomes, so awareness of risk factors and symptoms is crucial. If you or someone you know is experiencing these symptoms, it’s essential to consult a healthcare professional for further evaluation and testing.
