Question

Which of the following is not a characteristic of a benign tumor?

1) The tumor is harmless.
2) The tumor is encapsulated.
3) The tumor cells do not perform a useful function.
4) The tumor grows by infiltrating other brain regions.
5) The tumor has a distinct border.

Answer 1

The statement 'The tumor grows by infiltrating other brain regions' is not characteristic of a benign tumor, as benign tumors do not invade nearby tissues and remain localized.

Step-by-step explanation:

The characteristic that is not a feature of a benign tumor is that 'The tumor grows by infiltrating other brain regions.'

This is not a characteristic of a benign tumor. Benign tumors are localized and do not invade other tissues or grow uncontrollably. They typically have a distinct border and are encapsulated.

Benign tumors are generally encapsulated, have distinct borders, and do not invade or infiltrate nearby tissues or structures. While the cells in a benign tumor may not perform a useful function, they differ from malignant tumors as the latter are characterized by their invasive growth and potential to metastasize to other parts of the body. In contrast, benign tumors remain localized and do not harm health in the same way malignant tumors can.
