Hello Marian.
It does seem strange that you have paraproteins so high, and increasing, without more intensive investigation. In my case with MGUS and an increased reading of something like 10 they called me in unexpectedly, which caught me unawares. It turned out to be nothing but your results are very high.
The term ‘asymptomatic’ is interesting as I would normally think of physical symptoms when it’s mentioned but I understand that it could also include other blood results, but I always take the paraprotein level as the baseline marker for myeloma activity (or flc’s if it’s free light chain myeloma). I know they perform broad range blood tests looking out for increased levels of calcium (bone damage) and eGFR (kidney damage) and many others, but it would be nice for you to know the reason for holding back on treatment.
I doubt you can have ever-increasing levels that won’t eventually do you harm, but maybe they want to know where it is affecting you/will affect you, before they treat it. From my own non-myeloma experience I know that sometimes the treatment can be worse than the ailment, but knowing their strategy would be useful to you.
