What Is Lung Cancer?
Lung cancer is a type of cancer that starts in the lungs, one of the most vital organs responsible for oxygenating the blood. It is one of the most common cancers worldwide and a leading cause of cancer-related deaths. However, with advancements in early detection and treatment, survival rates have improved significantly.
Common Symptoms of Lung Cancer
Early-stage lung cancer may not show noticeable symptoms, which is why regular health check-ups are important. As the disease progresses, common symptoms may include:
-
Persistent cough that worsens over time
-
Chest pain that is constant or worsens with deep breaths or coughing
-
Coughing up blood
-
Shortness of breath
-
Hoarseness
-
Unexplained weight loss
-
Fatigue
-
Frequent lung infections like pneumonia or bronchitis
Note: If you or someone you know experiences these symptoms, seek medical advice promptly.
Major Causes and Risk Factors
Lung cancer can affect anyone, but certain factors increase the risk:
-
Smoking: The leading cause of lung cancer, accounting for about 85% of cases.
-
Secondhand smoke exposure
-
Prolonged exposure to harmful substances such as asbestos, radon gas, and industrial chemicals
-
Air pollution
-
Family history of lung cancer
-
Pre-existing lung diseases like COPD or pulmonary fibrosis
Quitting smoking and avoiding environmental pollutants significantly reduces the risk.
Types of Lung Cancer
There are two primary types:
1. Non-Small Cell Lung Cancer (NSCLC)
The most common type, making up about 85% of cases. It grows and spreads more slowly than small cell lung cancer.
2. Small Cell Lung Cancer (SCLC)
More aggressive and spreads quickly. It is closely associated with heavy smoking.
How Is Lung Cancer Diagnosed?
Early diagnosis is key to effective treatment. Doctors may use several tests, including:
-
Chest X-rays
-
CT scans
-
PET scans
-
Bronchoscopy
-
Biopsy
-
Sputum cytology
At Eden Critical Care Hospital, our advanced imaging and diagnostic labs help in accurate and timely detection of lung diseases.
Treatment Options
Treatment depends on the type, stage, and overall health of the patient. Common approaches include:
-
Surgery: Removal of cancerous tissue when detected early
-
Chemotherapy: Drugs to kill or slow the growth of cancer cells
-
Radiation therapy: High-energy rays to destroy cancer cells
-
Targeted therapy: Medications that attack specific cancer genes or proteins
-
Immunotherapy: Boosting the body’s immune system to fight cancer
Our pulmonologists and oncologists work closely to tailor the best treatment plan for every patient.
Importance of Early Detection
Lung cancer is most treatable when caught early. Routine screenings, especially for high-risk individuals like smokers or those with a family history, can save lives. Low-dose CT scans are often used for early detection.
