Lung cancer is a serious disease and one of the leading causes of cancer-related deaths worldwide. It occurs when abnormal cells grow uncontrollably in the lungs, forming tumors that may spread to other organs.

Main Cause: Smoking
Smoking is the primary cause of lung cancer. Cigarettes, bidis, pipes, and other tobacco products contain toxic chemicals that damage lung cells and significantly increase cancer risk. These harmful substances cause DNA mutations, leading to cancerous cells.

How Smoking Causes Lung Cancer:

  • Toxic Chemicals: Smoke contains thousands of chemicals that injure lung tissue and alter DNA, triggering cancer.

  • Damage to Cilia: Smoking harms the tiny hair-like structures called cilia that help clear dirt and bacteria from the lungs. Damaged cilia allow harmful substances to accumulate, raising cancer risk.

  • Weakened Immunity: Smoking weakens the body’s defense system, reducing its ability to fight cancer cells effectively.

Other Causes of Lung Cancer Besides Smoking:

  • Passive Smoking: Inhaling smoke from others also increases lung cancer risk.

  • Radon Gas: A radioactive gas from the soil that can accumulate indoors and cause lung cancer.

  • Asbestos Exposure: A mineral linked to a higher risk of lung cancer.

  • Family History: People with a family history of lung cancer have an elevated risk.

Symptoms of Lung Cancer:

  • Persistent cough

  • Coughing up blood

  • Shortness of breath

  • Chest pain

  • Fatigue

  • Unintended weight loss

  • Loss of appetite

Prevention Tips:

  • Quit Smoking: The most effective way to reduce lung cancer risk.

  • Avoid Passive Smoke: Stay away from smokers and smoky environments.

  • Reduce Radon Levels: Test and lower radon gas in homes.

  • Regular Checkups: Consult your doctor for regular screenings and follow medical advice.

Conclusion
Smoking is the leading cause of lung cancer, but quitting and leading a healthy lifestyle can significantly lower your risk. If you experience any symptoms mentioned, seek medical attention promptly. Evercare Hospital Chattogram is committed to providing expert care and support for lung health.
