Hi @mandm4evers, I wasn’t sure if you’re responding to @gingerw or my reply regarding repetitive bone marrow biopsies. But that won’t change the answer. (Hint, in the future just toss in the person’s @name such as @mandm4evers and the person will get tagged. ☺️)

In my case I had an aggressive blood cancer called AML. During and after treatment for the cancer and after a bone marrow transplant, frequent tests were needed to make sure there were no more cancer cells and that my transplant worked.
Ginger’s story is different. She has multiple myeloma but the scenario is the same. Doctor’s use the marrow biopsies to go directly to the blood manufacturing source to rule out, diagnose or check the progression of a disease of the blood.

In your case, you have more protein in your blood than the norm, so they’re checking your core cells to see if they can detect an issue in the ‘factory’. ☺️ This may be the only one you need or, there may be a few more in your future depending on the results. It’s an invaluable diagnostic tool for a hematologist.
As you can see, each person’s situation is unique to them so no fretting about what ifs. 🙃 The thought of the biopsy is worse than they are in reality. Knowledge is power. So if your doctor is suggesting a bmbx, then it’s a good place to begin the investigation along with the lab work.
Does this make sense?
