Lung Cancer
Lung cancer is a common and deadly disease that primarily affects the cells lining the air passages. It is categorized into non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). Smoking is the leading cause, but other factors like genetics and exposure to certain substances increase the risk. Early-stage lung cancer often shows no symptoms, but as it progresses, symptoms like cough, chest pain, and weight loss may appear. Diagnosis includes imaging tests and biopsies. Treatment

Introduction
Lung cancer is a malignant condition that develops in the lung tissue, primarily in the cells lining the air passages. It is one of the most common types of cancer, and a leading cause of cancer-related deaths worldwide.
Types of Lung Cancer
There are two main types of lung cancer: Non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). NSCLC is the most common type, accounting for around 85% of all lung cancer cases. SCLC, although less common, tends to grow and spread more quickly than NSCLC.
Causes and Risk Factors
The primary cause of lung cancer is smoking, with about 85% of all cases attributed to tobacco use. Exposure to secondhand smoke, radon gas, asbestos, and other occupational hazards also significantly increase the risk of developing lung cancer. Certain genetic mutations and a family history of lung cancer may predispose individuals to the disease.
Signs and Symptoms
Early-stage lung cancer often presents no symptoms, making it difficult to detect in its initial stages. However, as the disease progresses, common signs and symptoms may include:
Chronic cough that worsens over time
Chest pain or discomfort
Coughing up blood
Unexplained weight loss
Fatigue
Shortness of breath
Diagnosis
To diagnose lung cancer, various tests and procedures are employed, including:
Chest X-ray and computed tomography (CT) scan
Sputum cytology to examine expelled mucus for cancer cells
Lung biopsy to collect a tissue sample for analysis
Positron emission tomography (PET) scan to determine the extent of the disease
Treatment
The choice of treatment for lung cancer depends on several factors, such as the type and stage of cancer, overall health, and individual preferences. Treatment options may include:
Surgery to remove the tumor and nearby affected tissue
Chemotherapy to kill cancer cells using medications
Radiation therapy to target and destroy cancer cells with high-energy rays
Immunotherapy to stimulate the immune system to fight cancer cells
Targeted therapy to block specific abnormalities within cancer cells
Prevention
While not all cases of lung cancer can be prevented, certain lifestyle changes can help reduce the risk:
Avoid smoking and tobacco use
Minimize exposure to secondhand smoke and environmental pollutants
Test homes for radon gas and take necessary measures to reduce exposure
Follow proper safety guidelines when working with asbestos or other hazardous substances
Maintain a healthy lifestyle with regular exercise and a balanced diet
Conclusion
Lung cancer is a serious and potentially life-threatening condition that necessitates early detection and timely intervention. Understanding the causes, symptoms, and available treatment options is essential for improving outcomes and reducing the impact of this disease on individuals and society as a
