தலை மற்றும் கழுத்து புற்றுநோய் – காரணங்கள்?? | Dr Vignesh ENT

Описание: 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”? (sites; mostly squamous cell)
00:35 Major causes: smoking, alcohol, betel nut/leaf (paan)
01:10 Dose + duration matter; smoking + alcohol = much higher risk (≈5–25× vs non-smokers)
01:45 “I quit—am I safe now?” Risk falls, but remains higher than never-smokers
02:10 How carcinogens cause cancer: DNA damage → abnormal cell growth
03:00 HPV and oropharyngeal cancer; sexual transmission; rising in developed regions; younger patients
04:05 EBV and nasopharyngeal cancer; saliva spread; can stay silent for years
05:10 Who’s at extra risk? Low immunity, genetics, poor diet/oral hygiene, chronic infections
06:00 Prevention pointers: avoid tobacco/alcohol, don’t combine them, maintain oral health, seek early evaluation

Key Takeaways
• Head & neck cancers mostly arise from squamous cells lining ENT structures.
• Smoking, alcohol, and betel nut/leaf are the commonest causes; amount + years determine risk.
• HPV (oropharynx) and EBV (nasopharynx) can drive cancer—often after long dormancy plus other risk factors.
• Quitting helps, but prior heavy exposure means risk doesn’t drop to zero—prevention and follow-up matter.
