Which of the following characteristics is associated with malignant tumors?

Both (a) and (b)

a- Metastasis

b-Uncontrolled cell division

c-Both (a) and (b)

d-Controlled cell division

Malignant tumors possess both the properties of metastasis and uncontrolled cell division.

Metastasis refers to the ability of cancer cells to spread and establish secondary tumors in different parts of the body. Malignant tumors have the capacity to invade nearby tissues and enter the bloodstream or lymphatic system, allowing them to travel to distant sites and form new tumors. This ability to metastasize is a key characteristic of malignant tumors and is responsible for the spread of cancer throughout the body.

Uncontrolled cell division is another characteristic of malignant tumors. Unlike normal cells, which undergo regulated cell division to maintain tissue homeostasis, cancer cells divide in an uncontrolled manner. They ignore the signals that control cell growth and division, leading to the formation of a mass of abnormal cells. This uncontrolled growth can result in the development of a tumor and the subsequent disruption of normal organ function.

Therefore, the correct answer is option (c) - Both (a) and (b), as malignant tumors possess the properties of metastasis and uncontrolled cell division.
