Spread of multiple myeloma
Multiple myeloma is usually widespread by the time it is diagnosed. It affects multiple (more than 1) bones or multiple areas of a bone.
The most common bones where multiple myeloma occurs include:
- spine (vertebrae)
- breastbone (sternum)
- shoulder blade (scapula)
- upper arm bone (humerus)
- upper leg bone (femur)
Doctors measure substances in the blood or urine to see if the disease is progressing, or getting worse. This includes measuring levels of:
- monoclonal protein (M-protein)
