Cancer cells differ from normal cells in terms of contact inhibition because:
| 1. | Cancer cells show enhanced contact inhibition, stopping division more readily than normal cells. |
| 2. | Cancer cells have lost the property of contact inhibition and continue dividing even when in contact with other cells. |
| 3. | Cancer cells develop contact inhibition only in the presence of growth factors. |
| 4. | Cancer cells show contact inhibition only with cells of the same type. |

Cells sloughed from malignant tumors reach distant sites through blood, and wherever they get lodged in the body, they start a new tumor there. This property is called:
1. Oncogenic transformation
2. Contact inhibition
3. Metastasis
4. Metaplasia

The malignant nature of cancerous tumours is mainly attributed to their ability to undergo metastasis, which involves:
| 1. | Rapid but localised cell division at the site of origin |
| 2. | Formation of benign growths enclosed within connective tissue |
| 3. | Spread of cancer cells from the primary site to distant organs |
| 4. | Replacement of normal cells through controlled differentiation |
