Bone metastasis (plural; metastases) is the formation of cancerous cells inside bone. Bone metastases are usually caused by secondary metastases. It is a complex system that the cells undergo to inhabit the bone:
Cancerous cells undergo loss of intracellular cohesion, basically they lose the ability the stick together and also generate their own blood supply. Cancer cells then need to enter the blood system and survive. they attach themselves to blood cells and platelets and regain the ability of intracellular cohesion. when they reach the destination, they escape the blood supply; this process is called extravasion (the forcing of fluid out of a vessel) in this case out of the vein's, and into the target organ (in this case bone - intravasion). They then must evade capture by the immune system. They do this by sending out biological signals to prevent the immune system from fighting the cells. they then begin the process of doubling again and again.
To understand the biological effects on the bone look at coupled remodelling, which is a process run in equilibrium of normal bone oblation and remodelling until the bone metastases interfere with this process.

Does bone cancer commonly start in the bone?
Actually, the opposite is true. Approximately 80% of bone cancers are secondary, such as metastasis from primary tumors in soft tissue. Only about 20% of bone cancers actually start in the bone and then metastasize to soft tissues and other locations.
Can you get bone cancer in big toe bone?
Yes, you can get cancer anywhere! The big toe is a common place for the metastasis of other cancers to occur. Ex) Late stage lung cancer spreads commonly to the big toe. -Physician Assistant Student.

What are the cancer cells called that break free and travel?
This process is called metastasis.

Is spindle cell sarcoma benign or malignant?
Telengiectatic osteogenic sarcoma is a malignant condition. Telengiectatic ostegenic sarcoma is usually caused by metastasis from pelvic malignancy that has spread to the bone.
What is metastasis?
Metastasis is the spread of a disease from one organ or part to another non-adjacent organ or part.
Is Myelophthisic anemia the same as leukoerythroblastic anemia?
A myelophthisic anemia is the displacement of the bone marrow into the peripheral circulation by a disease such as metastasis of the bone marrow. This leads to the presence of nucleated RBCs and immature myeloid cells in the peripheral blood. Under microscopy, this is known as "leukoerythroblastic smear."
