A clear, patient-friendly explainer on what counts as head & neck cancer (ear, nose, throat, neck, and salivary-gland regions—most are squamous cell carcinomas) and why they happen. Dr Vignesh covers the big risk factors—smoking, alcohol, betel nut/leaf—how dose + duration drive risk, and why smoking + alcohol together multiplies danger. He also explains HPV-related oropharyngeal cancers (often in younger, non-smokers) and EBV-related nasopharyngeal cancer, plus how viruses can lie dormant and turn malignant when immunity is low, nutrition/oral hygiene are poor, or genetics add risk. Chapters (06:40) 00:00 What is “head & neck cancer”?
