Lung Cancer
Lung cancer is a type of cancer that begins in the cells of the lungs. It is one of the most common cancers worldwide and a leading cause of cancer-related deaths. Lung cancer can be categorized into two main types: non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC), each with its characteristics and subtypes.
Here are some key points about lung cancer:
Risk Factors:
- Smoking: Tobacco smoking is the leading cause of lung cancer. It's responsible for the majority of lung cancer cases.
- Secondhand Smoke: Exposure to secondhand smoke can also increase the risk.
- Radon Gas: Prolonged exposure to radon, a naturally occurring radioactive gas, is a significant risk factor.
- Occupational Exposures: Certain occupations, such as asbestos-related industries, can increase the risk.
- Family History: A family history of lung cancer may elevate the risk.
- Air Pollution: Long-term exposure to high levels of air pollution can be a contributing factor.
Symptoms:
Common symptoms of lung cancer include:
- Persistent cough
- Coughing up blood
- Chest pain
- Shortness of breath
- Hoarseness
- Unexplained weight loss
- Fatigue
- Recurrent respiratory infections
Diagnosis :
Lung cancer is typically diagnosed through a combination of methods, including:
- Imaging tests like chest X-rays, CT scans, and PET scans.
- Sputum cytology (examining mucus from the lungs for cancer cells).
- Biopsy (removing a sample of lung tissue for examination).
Staging:
Lung cancer is staged from Stage 0 (localized to the lungs) to Stage IV (spread to distant organs). Staging helps determine the extent of the cancer and guide treatment decisions.
Treatment:
Treatment options for lung cancer depend on the type, stage, and overall health of the patient. They may include:
- Surgery: To remove the tumor or part of the lung.
- Radiation therapy: Using high-energy X-rays to target cancer cells.
- Chemotherapy: Medications that kill cancer cells throughout the body.
- Targeted therapy: Drugs that target specific genetic mutations in cancer cells.
- Immunotherapy: Boosting the immune system to fight cancer cells.
Prognosis:
The prognosis for lung cancer varies widely based on the stage at diagnosis and the specific type of lung cancer. Early-stage lung cancer is more treatable and has a better prognosis than advanced-stage cancer.
Prevention:
It’s important for individuals to seek medical attention if they experience symptoms suggestive of lung cancer, especially if they have known risk factors. Early detection and intervention can significantly improve treatment outcomes. Additionally, smoking cessation and adopting a healthy lifestyle can reduce the risk of developing lung cancer.

Lung Cancer Overview
Lung cancer is a type of cancer that begins in the cells of the lungs. It is one of the most common cancers worldwide and a leading cause of cancer-related deaths. Lung cancer can be categorized into two main types: non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC), each with its characteristics and subtypes.
Non-Small Cell Lung Cancer (NSCLC)
NSCLC accounts for about 85% of all lung cancer cases. It includes subtypes such as adenocarcinoma, squamous cell carcinoma, and large cell carcinoma.
