Lung Cancer
Lung Cancer
Lung cancer is one of the most prevalent and serious forms of cancer worldwide, affecting millions of individuals each year. It primarily develops in the lungs’ cells and is often linked to long-term tobacco use, though non-smokers can also be affected due to factors like air pollution, genetic predisposition, and occupational hazards. A distinguished Surgical Oncologist, emphasizes the importance of early detection and timely intervention in managing lung cancer effectively. Symptoms such as persistent cough, shortness of breath, chest pain, and unexplained weight loss should not be ignored, as early-stage lung cancer often presents with minimal or no symptoms. Advances in medical research and treatment options, including surgery, radiation therapy, targeted therapy, and immunotherapy, have improved patient outcomes significantly.
Understanding the risk factors, adopting preventive measures, and seeking expert medical guidance play a crucial role in the fight against lung cancer.
Symptoms of Lung Cancer include
- Persistent cough
- Blood in sputum (spit or phlegm)
- Shortness of breath either on exertion or at rest
- Chest pain
- Change in voice
- Tobacco smoking (causes 60-65 per cent of lung cancers)
- Exposure to second-hand or passive smoking
- Exposure to radon gas, asbestos and other carcinogens
- Family history of lung cancer
- Stage I: Cancer is confined to lung
- Stage II/III: Cancer is confined to chest
- Stage IV: Cancer spreads to other organs (lymph nodes, brain, liver, adrenal glands)
- Stage I/II – Surgery can be considered
- Stage III – Combination of surgery, chemotherapy and radiation therapy may be required
