Question

What does the formation of a malignant tumor indicate?

a. Mitotic rates of cells are no longer responding to normal control mechanisms.
b. The tumor cells resemble normal cells, but they are dividing faster.
c. Metastasis is necessary and easy to control.
d. The cells are remaining within a connective tissue capsule.

Answer 1

A malignant tumor suggests unregulated cell division, potential invasion of nearby tissues, and the possibility of metastasis as cancer cells spread to other body parts.

Step-by-step explanation:

The formation of a malignant tumor indicates that the mitotic rates of cells are no longer responding to normal control mechanisms. These cells exhibit uncontrolled growth and can invade surrounding tissues, leading to the potential spread of cancer cells to other parts of the body—a process known as metastasis. Unlike benign tumors, which are localized and can usually be removed without much harm, malignant tumors are cancerous and their growth is not constrained within a connective tissue capsule.
