Interleukin -2 and alpha interferon are showing promise in the treatment of cancers. They are:
1. | Immunostimulants | 2. | Phagocytes |
3. | Chemotherapeutic agents | 4. | Radiotherapeutic agents |
Plants do not have cancers as:
1. | they do not have circulation |
2. | they have highly developed immunity against them |
3. | the plant cells have cell walls |
4. | they already have meristems at their tips |

Consider the following statements:
I: | Cancer is essentially a genetic disease caused by multiple mutational events. |
II: | Cancerous cells are rapidly dividing cells that exhibit contact inhibition. |
III: | Metstatsis is the most feared complication of any cancer. |
Which of the above statements are true?
1. | I and II only | 2. | I and III only |
3. | II and III only | 4. | I, II, and III |
In malignant tumors, the cells proliferate, grow rapidly, and move to other parts of the body to form new tumors. This stage of the disease is called:
1. | metagenesis | 2. | metastasis |
3. | teratogenesis | 4. | mitosis |
