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.

When cancer cells undergo metastasis, they spread from the original (primary) tumor to other parts of the body through the bloodstream or lymphatic system. Once they settle in a new location, they can grow and form secondary tumors, also called metastatic tumors. For example: Breast cancer that spreads to the bones forms metastatic breast cancer, not bone cancer. Lung cancer that spreads to the liver is called metastatic lung cancer, even though the new tumor is in the liver. Metastasis commonly affects organs such as: Lungs Liver Bones Brain The development of secondary tumors can make cancer more difficult to treat because it involves multiple areas of the body. Early detection and timely treatment of the primary cancer can help reduce the risk of metastasis in some cases.
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

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.

Cancer cells undergo uncontrolled cell division primarily through a process called mitosis. Unlike normal cells, which regulate their division to maintain tissue homeostasis, cancer cells often bypass these regulatory mechanisms, leading to rapid proliferation. This unregulated mitosis can result in the formation of tumors and the spread of cancer to other parts of the body through a process known as metastasis.
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.
Breast cancer generally develops in a gradual sequence, although the exact progression can vary from person to person. The typical order is: Genetic or DNA changes occur in breast cells. Abnormal cells begin to grow uncontrollably. A localized tumor forms within the breast tissue or milk ducts. The tumor grows and may invade nearby breast tissue. Cancer may spread to nearby lymph nodes, especially those under the arm. Metastasis may occur, where cancer cells spread through the blood or lymphatic system to distant organs such as the bones, lungs, liver, or brain. In summary, the general progression is: DNA mutations → Abnormal cell growth → Tumor formation → Local invasion → Lymph node involvement → Metastasis (advanced stage) Early detection through regular breast screenings, breast self-awareness, and prompt medical evaluation of symptoms can improve treatment outcomes.
