I have never heard of removing or killing off the spleen. I dont have an opinion to offer. But you are right about difficult decisions. I hope someone comes along to offer advice and insight, but I really cant remember anyone who has had this problem.
And as to the decision, you will make the one that is best for you. You cant go back and question your decisions. Everyone makes choices based on what the know and what they feel. Every decision we make in regards to cc is a gamble. It is a sneaky disease and doesnt play fair. So whatever decision you make, it is the right one for you at the time and that is the best we can all do.
