Persistent cough, breathlessness, blood in sputum, chest pain, weight loss, and fatigue are common signs of lung cancer. Early evaluation, low-dose CT screening for high-risk people, accurate diagnosis with biopsy, and molecular testing guide modern treatment options including surgery, radiation, chemotherapy, targeted drugs, and immunotherapy.
Lung cancer often shows no early symptoms, so screening and prompt evaluation are critical. Modern care combines surgery, radiation, chemotherapy, targeted drugs, and immunotherapy based on tumor type, stage, and molecular markers. Clinical trials and symptom-focused care remain central to treatment.
Virtual colonoscopy (CT colonography) uses low-dose CT and 3D imaging to screen the colon with less invasiveness than conventional colonoscopy. It detects polyps and cancers but cannot remove lesions - positive findings require traditional colonoscopy.
