How is multiple myeloma diagnosed?

Multiple myeloma is not always easy to diagnose. There is no one test to be performed. Instead, doctors consider many things, like symptoms you may be feeling and the results from a variety of tests.

What is C.R.A.B. ?

C.R.A.B. is an acronym used to describe the most common signs and symptoms of multiple myeloma. It stands for Calcium, Renal, Anemia, and Bone. Because multiple myeloma weakens the body’s defense system (the immune system), it may also be accompanied by infections.

 

Common signs and symptoms of multiple myeloma:

Calcium

Too much calcium in your blood

  • You may feel very tired or confused. 
  • You may feel nauseated or even vomit. 
  • You may lose your appetite. 
  • You may urinate more often.

Renal

Kidney problems, sometimes called renal problems

  • You may feel very tired or confused. 
  • You may feel nauseated or even vomit. 
  • You may lose your appetite, urinate more often, and have high blood pressure.

Anemia

Too few oxygen-carrying cells in your blood 

You may feel very tired or dizzy, have headaches often, get out of breath easily, or feel cold frequently.

Bone

Bone problems

You may feel bone pain, which may be a sign of bone fractures.
