Which of the following is NOT a typical difference factor between benign and malignant tumors?
Which of the following is NOT a typical difference factor between benign and malignant tumors? Correct Answer size of the tumor
Explanation:-
- Size of the tumor is not a typical difference factor whereas characteristics such as growth rate, encapsulation, cell differentiation, the morphology of cells, and treatment differ.
Table Key Features of benign and malignant tumors
| Benign Tumors | Malignant tumor |
| Cells tend not to spread | Cells can spread |
| The rate of cell division is slow (cell differentiation) | Cell division is uncontrolled and abnormal |
| The tumor is confined to a specific, localized area (Encapsulation) | Mostly, malignant tumors are not encapsulated. |
| Do not metastasize (spread) to other parts of the body | Often invade basal membrane that surrounds nearby healthy tissue. Can spread via bloodstream or lymphatic system |
| Shape, chromosomes, and DNA of cells appear normal | Cells have abnormal chromosomes and DNA characterized by large, dark nuclei; may have an abnormal shape |
| Do not secrete hormones or other substances (except pheochromocytomas) | Can secrete substances that cause fatigue and weight loss (paraneoplastic syndrome) |
