Question

what is the process called when a malignant tumor spreads to other parts of the body?
transplant
diffusion
metastasis
mitosis

Explanation:

• Transplant: It refers to the act of moving an organ or tissue from one body to another or from one part of a body to another. It is not related to the spread of a malignant tumor.
• Diffusion: In a biological context, it is the movement of molecules from an area of higher concentration to an area of lower concentration. This is not the process of a malignant tumor spreading.
• Metastasis: This is the process by which cancer cells break away from the original (primary) tumor, travel through the blood or lymph system, and form new tumors (metastatic tumors) in other parts of the body.
• Mitosis: It is a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus. It is a normal cell - division process for growth and repair, not for tumor spread.

Answer:

metastasis
