Lung Cancer
Lung Cancer: Causes, Symptoms, and Treatment
What is Lung Cancer?
Lung cancer is a serious disease that develops in the lungs and is the leading cause of cancer-related deaths worldwide. It occurs when abnormal cells grow uncontrollably in the lung tissues, affecting breathing and overall lung function.
Causes of Lung Cancer
The primary cause of lung cancer is smoking, responsible for about 85% of cases. Other risk factors include:
- Exposure to harmful chemicals in pollution or certain workplaces
- Genetic mutations that damage lung cells
- Long-term exposure to secondhand smoke
- Daily alcohol consumption
Common Symptoms of Lung Cancer
Lung cancer symptoms may not appear in the early stages but can include:
✔️ Persistent cough or worsening cough
✔️ Chest pain or discomfort
✔️ Shortness of breath or wheezing
✔️ Coughing up blood
✔️ Hoarseness
✔️ Unexplained weight loss
✔️ Chronic fatigue
Types of Lung Cancer
There are two main types of lung cancer:
🔹 Non-Small Cell Lung Carcinoma (NSCLC) – More common and grows slowly
🔹 Small Cell Lung Carcinoma (SCLC) – Less common but aggressive and spreads quickly
Diagnosis and Treatment
- Early detection through screening can improve survival rates, especially in high-risk individuals.
- Treatment depends on the cancer type, stage, and medical history of the patient. Common treatment options include surgery, chemotherapy, radiation therapy, targeted therapy, and immunotherapy.
