Hi Welcome to the WhatNext Forum.
Yeah, WM is very rare. That Bendamsutine/Rituxan is pretty easy (easier and more effective than the alternative, R-CHOP). At least it should be. Rituxan is the wild card. It's generally easy, you will probably find it so, but some have more severe reactions. They're endurable, though. Slow down the rate of Rituxan infusion if you have a problem. Hopefully, you won't have a reaction as severe as mine (very rare) but, if you do, there is a regimen that will help. I'll get my second Rituxan infusion with that regimen tomorrow. You should have very little reaction to Bendamustine. You won't lose your hair.
Have you come across the International Waldenstrom Macroglobulinemia Foundation?
