| Statement I: | Cancer is caused by multiple mutational events in almost all cases. |
| Statement II: | Some viral infections can also cause cancer in humans. |
| I: | Benign tumors normally remain confined to their original location and do not spread to other parts of the body and therefore, cause little damage. |
| II: | The malignant tumors are a mass of proliferating cells called neoplastic or tumor cells and spread to other parts of the body. |
