1. What is the cellular origin?Tumours originate from genetic and epigenetic alterations in normal cells
2. What is the hallmarks of cancer?Malignant tumours exhibit characteristics like sustained proliferation and invasion
3. What is the difference between a benign and a malignant tumour?Benign tumours stay in one place and don’t invade other tissues. Malignant tumours can grow into nearby tissues and travel to other parts of the body, which is why they are called cancer.
4. How do tumours grow?Tumours grow when cells keep dividing instead of stopping or dying. This happens because the genes that control cell growth get changed or turned off.

Neoplasm: An abnormal mass of tissue resulting from uncontrolled cell growth, synonymous with tumour.
