Lung Cancer

Overview

Lung cancer is a malignant tumor originating in lung tissue, most often caused by DNA damage to airway cells from inhaling tobacco smoke or harmful chemicals. Early-stage disease is usually asymptomatic, while advancing disease causes cough, shortness of breath, and chest pain. About 85% of cases are non-small cell lung cancer and 15% are small cell lung cancer.

Symptoms

• Cough
• Coughing up blood
• Chest pain
• Shortness of breath
• Weight loss

Treatment

Requires comprehensive treatment after specialist evaluation. Early-stage disease is treated primarily with surgery, while intermediate to advanced stages may combine radiotherapy, chemotherapy, and targeted or immunotherapy.

Dietary advice

Ensure adequate intake of high-quality protein and calories, eat small frequent meals, and consume plenty of fresh fruits and vegetables for nutritional support.
