diagnosed a few months ago, responding well to Velcade+dex. Trying to learn more about MM, but overwhelmed with info. Have visited many websites and watched many youtubes about MM but come away bewildered, confused by "free light chains" the Greek letters and all the other mysteries. Question is, as we are have confidence in our hematologist, is it really important to know whether it is alpha or beta or delta or gamma? We get a report each week on the boodwork, which consists of a full page of 3-letter acronyms followed by a number. We know that RBC means red blood cells, and can see that they are running a little low, but we don't know how to read the alphabet soup of letters and numbers that fill the page. Is it really necessary to understand all that stuff if the MDs and nurses are doing their jobs? We don't have the skills to second-guess them, anyway. Thank you.
