Cells do undergo mitosis regularly. This is because cells are always dying and need to be replaced. However, there are certain cells that are commanded by the brain, or have special genetic coding that instructs them to stop multiplying. For instance, cells in the nervous system and spine do not multiply after birth. That is why damage to the spine is so irreversible.
Cancer cells are abnormal in that they do not respond to the body's internal and external symbols. When normal cells touch other cells, they stop dividing but, cancer cells don't stop dividing. They pile up causing many problems.
Metastasis is a common word used when referring to cancer. If something is said to have metastisized it means that it is on the move in the body, moving from location to location. This causes the tumor, clot, or cancer to be able to spread throughout the body, thus effecting more of the body and killing is sooner.
Do people grow? Are you a multicellular organism? Do you have any cells in your body that can grow and shrink without dividing depending on conditions? FAT and MUSCLE cells do. Do you have any cells in your body that can replicate? Skin and epidermal cells do. Many other cells in the body can undergo some replication during a person's life. A common multicellular microorganism is MOLD. IT CAN GROW AND DIVIDE.

Malignant tumors
An additional mutation in a tumor cell that allows it to express proteinase can cause metastasis because it allows the cell to break down the underlying tissue and spread it to other areas. Metastasis

metastasis
The process of malignant cells moving throughout the body is called metastasis. Metastasis allows cancer cells to spread from the primary tumor to other parts of the body, where they can form new tumors.
The movement of cancer cells from one tumor to other areas is called metastasis.

Body cells do not undergo meiosis. Reproductive cells undergo meiosis, body cells, mitosis.
Prostate metastasis is when cancer cells in the prostate get into the lymph system and begin to travel to other organs of the body, spreading the cancer.
Invasion of cancer cells refers to the ability of cancer cells to penetrate and spread into nearby tissues. Metastasis, on the other hand, involves the spread of cancer cells from the primary tumor to distant organs or tissues in the body through the bloodstream or lymphatic system. Metastasis is a more advanced stage of cancer progression and is often associated with a poorer prognosis.
