Manageable is mainly a good word. Not the one we want but not bad either. I'm not in your situation, I can't pretend to know how it feels but I do have two lifelong side effects of cancer treatment. And both are manageable. They are an ever present part of my life but they don't rule it. They can be really irritating but not devastating. I can live my life. I don't know how long it will be, none of us do. But it's mine, it's there and I'm going to live every minute of it. My very best wishes for managing well.
