A crisp, patient-friendly intro to tumors in the head & neck. Dr Vignesh explains the difference between benign tumors (grow locally, don’t spread), malignant tumors (cancers that can invade/spread), and precancerous lesions (not cancer yet, but can turn into one). He also clarifies how cysts differ from tumors (fluid-filled sac vs solid mass), why tumors form (cell-cycle & DNA errors), and what raises risk (carcinogens such as tobacco, alcohol, UV light, chemicals, radiation)—with a reminder that exposure ≠ certainty because genetics and dose matter.
Chapters (04:53)
00:00 Intro—neck & earlobe “tumors” and the fear of cancer
00:25 Types of tumors: benign, malignant (cancer), precancerous lesions
01:05 Cyst vs tumor: fluid-filled sac vs solid growth (why they’re confused)
01:45 Why tumors form: normal cell life → DNA problem → uncontrolled growth
02:35 Carcinogens: tobacco (smoking/chewing), alcohol, UV, chemicals, radiation
03:35 Risk isn’t guaranteed: exposure level + genetic makeup = probability
04:10 What’s next in the series: ear, nose, throat & neck cancers
Key Takeaways
• Benign vs malignant vs precancerous—know the differences to avoid panic.
• Cysts ≠ tumors: cysts are sacs with fluid/air; tumors are solid cell growths.
• DNA changes drive abnormal growth; carcinogens increase probability.
• Exposure ≠ destiny: risk depends on dose and genetic makeup.
