Lung cancer
Lung Cancer
Lung cancer, a leading cause of cancer-related deaths worldwide, affects the lungs and can be significantly influenced by lifestyle choices, particularly smoking. It often begins in the cells lining the bronchi and parts of the lung such as the bronchioles or alveoli. Early detection through screening tests like low-dose CT scans can greatly improve outcomes, as symptoms may not manifest until the disease is advanced. Factors like quitting smoking, reducing exposure to secondhand smoke, and avoiding carcinogens play crucial roles in prevention.
Treatment options vary depending on the stage of cancer but may include surgery, chemotherapy, radiation therapy, targeted therapies, and immunotherapy. Increased awareness, coupled with regular screenings and healthy lifestyle choices, is paramount in combating this disease.
Risk Factors
- Smoking: The primary risk factor, significantly increasing the likelihood of developing lung cancer.
- Exposure to radon gas: A natural radioactive gas that can cause lung cancer with prolonged exposure.
- Family history: Individuals with close relatives who have had lung cancer are at a higher risk.
- Exposure to asbestos and other carcinogens: Occupational hazards can increase risk.
Symptoms
- Persistent cough that worsens over time
- Coughing up blood or rust-colored sputum
- Chest pain that is often worse with deep breathing, coughing, or laughing
- Hoarseness and shortness of breath
Diagnosis
- Screening tests: Low-dose CT scans are commonly used for high-risk individuals.
- Diagnostic tests: Biopsy, bronchoscopy, imaging tests like CT scans or MRIs, and PET scans may be performed to determine the extent and stage of the cancer.
Treatment
- Surgery: Removal of the tumor and surrounding tissue is the primary treatment for localized lung cancer.
- Chemotherapy: Drugs are used to kill cancer cells or stop them from growing.
