Positron Emission Tomography (PET) Scan
A PET scan is a procedure that is used to find malignant tumor cells in the body. A small amount of radionuclide glucose (sugar) is injected into a vein and the PET scanner rotates around the body and makes a picture of where the glucose is being used in the body. Malignant tumor cells show up brighter in the picture because they are more active and take up more glucose than normal cells.
Bone densitometry is a procedure that uses a special type of x-ray to measure bone loss.
Specific stages of multiple myeloma include:
- Stage I
- Stage II
- Stage III.
The higher the stage number, the higher the number of myeloma cells in the body. The number of myeloma cells in the body is determined by:
- The level of hemoglobin in the blood
- The levels of calcium and creatinine in the blood
- The amount of bone damage
- The amount of antibody M protein in the blood or urine.
The multiple myeloma stage also takes into account whether the cancer is causing problems with your bones or kidneys.
Multiple Myeloma: Stage I
In stage I multiple myeloma, there is a low number of myeloma cells in the body.
Multiple Myeloma: Stage II
In stage II multiple myeloma, there is a moderate number of myeloma cells in the body.
Multiple Myeloma: Stage III
In stage III multiple myeloma, there is a large number of myeloma cells in the body.
