Cancer cells exhibit:
| 1. | Contact inhibition | 2. | Low division rate |
| 3. | Metastasis | 4. | High degree of differentiation |

Metastasis shown by malignant tumors:
| 1. | is due to contact inhibition exhibited by cells. |
| 2. | causes cells to remain undifferentiated. |
| 3. | makes cancer cells susceptible to be killed by radiation. |
| 4. | can start secondary tumors at distant sites in the body. |
