Lung Cancer: Causes, Symptoms, Diagnosis & Treatment

Lung cancer is a serious disease that begins in the lungs, often due to genetic mutations in lung cells. These mutations cause uncontrolled cell growth, forming tumors that can spread to other parts of the body. It is one of the most common cancers worldwide and is a leading cause of cancer-related deaths.

Several factors contribute to the development of lung cancer, including:

  • Smoking: The leading cause, responsible for about 85% of cases.

  • Secondhand Smoke: Inhalation of smoke from other smokers increases risk.

  • Exposure to Carcinogens: Radon gas, asbestos, and air pollution can elevate risk.

  • Genetic Factors: A family history of lung cancer may increase susceptibility.

  • Previous Lung Diseases: Chronic obstructive pulmonary disease (COPD) or pulmonary fibrosis can contribute.

Lung cancer symptoms often appear in later stages and may include:

  • Persistent cough that worsens over time

  • Chest pain, especially when breathing deeply or coughing

  • Shortness of breath

  • Unexplained weight loss

  • Coughing up blood (hemoptysis)

  • Hoarseness

  • Recurrent respiratory infections

Diagnosing lung cancer involves several tests and procedures, including:

  • Imaging Tests: Chest X-rays, CT scans, and PET scans to detect abnormalities.

  • Biopsy: A tissue sample is collected via bronchoscopy or needle biopsy for laboratory analysis.

  • Sputum Cytology: Examining mucus from the lungs for cancerous cells.

  • Molecular Testing: Identifying genetic mutations to determine targeted treatment options.

Lung cancer treatment depends on the type, stage, and patient’s overall health. Options include:

  • Surgery: Removing the tumor through procedures such as lobectomy, pneumonectomy, or segmentectomy.

  • Radiotherapy: High-energy radiation to destroy cancer cells, often used post-surgery or for non-operable cases.

  • Chemotherapy: Drug treatments to kill cancer cells, usually used in advanced cases.

  • Targeted Therapy: Medications designed to attack specific cancer cell mutations.

  • Immunotherapy: Boosting the body's immune system to recognize and destroy cancer cells.
