Which one of the following is not a property of cancerous cells, whereas the remaining three are?
| 1. | They compete with normal cells for vital nutrients |
| 2. | They do not remain confined in the area of formation |
| 3. | They divide in an uncontrolled manner |
| 4. | They show contact inhibition |
Which one of the following techniques is safest for the detection of cancers:
1. Radiography (X-ray)
2. Computed tomography (CT)
3. Histopathological studies
4. Magnetic resonance imaging (MRI)
Which one of the following statements is correct?
| 1. | Patients, who have undergone surgery are given cannabinoids to relieve pain |
| 2. | Benign tumours show the property of metastasis |
| 3. | Heroin accelerates body functions |
| 4. | Malignant tumours may exhibit metastasis |
Cancer cells are more easily damaged by radiation than normal cells because they are:
| 1. | Undergoing rapid division |
| 2. | Different in structure |
| 3. | Non-dividing |
| 4. | Starved of mutation |
Carcinoma refers to:
| 1. | Malignant tumours of the connective tissue |
| 2. | Malignant tumours of the skin or mucous membrane |
| 3. | Malignant tumours of the colon |
| 4. | Benign tumours of the connective tissue |
Cancerous cells can easily be destroyed by radiation due to the:
1. Rapid cell division
2. Lack of nutrition
3. Fast mutation
4. Lack of oxygen
