So sorry to hear your news. Statistics (good or bad) don't mean squat at this juncture. This is about you.

It will be hard to hang in there until Tuesday..but at least it is on Tuesday that you will have more answers. Small comfort, I know, since it is any waiting that is agonizing.

Some things to investigate / think about before then...
1) type of operation ... there are two methods and pros / cons with each. There are folks on here who have experience with each one and I'll bet they weigh in

2) you (and your surgeon) should probably discuss a few days of IVIG therapy for you before surgery. You will want to be as strong as possible.

While your family history is concerning and can not be discounted, try not to get too many steps ahead. First things first....meet the surgeon.

Talk to you soon
