I have Kappa Light chains of 44 but you can bet my Dr will be answering MY QUESTIONS when I get there next week. I'm new to this thing but I'm also an RN so I believe that one must advocate for themselves, ALWAYS! You are very important and don't forget that. I'm a 20 year colon cancer survivor and I've never stopped asking questions and proving that WE can beat the odds if we stand up for ourselves!
