Just wanted to weigh in here. I'm glad you are going to have the lap. done. I don't want to bore you with my story again if you remember it, but I had a cyst that was growing out of control and my doctor said it would shrink back down and not to worry about it. Right! It continued to grow and ended up cutting off the blood supply to my ovary. In the end I became deathly ill and had to have the ovary and cyst removed in an emergency surgery (on a Sunday morning, no less) So what I am trying to say is I would definitely want the cyst removed (and analyzed of course)because you just don't know what it might do. My 2 cents, your situation might not be like mine, but I do know that despite careful monitoring, cysts can change quickly and cause all sorts of problems.
Also, every time I have a cyst, the tech. will note that there is fluid in the abdominal cavity. It is not necessarily something to be extremely alarmed about. The body has some magical way of reabsorbing this. Although it does take awhile and I am usually very tender when this fluid is present. I think the question is how much? If there is a lot, it is more worrisome. Just before my above mentioned surgery, there was A LOT.
We will be thinking of you next week. Please post updates when you feel up to it.
