Bone Cancer (primary)
The bones
A typical healthy person has over 200 bones, which:
- support and protect internal organs
- are attached to muscles to allow movement
- contain bone marrow, which makes and stores new blood cells
- store proteins, minerals and nutrients, such as calcium.
Bone structure
Bones are made up of different parts, including a hard outer layer (known as cortical bone) and an inner core (known as trabecular bone). The bone marrow is found in this inner core. Cartilage is the tough material at the end of each bone that allows one bone to move against another at a joint.
Bones of the body
Bones commonly affected by primary bone cancer include the spine, ribs, pelvis and upper bones of the arms (humerus) and legs (femur).
