It really depends on how old you are and whether or not you still want to have children. I doubt having just the cyst removed will cause any problems with regards to this, but I have heard that even if a cyst is removed it can come back again and cause further problems. If you do not want to have any more children, then to be honest, I would suggest you talk to your doc about the possibility of having a hysterectomy. I had one when I was 34 and within a few weeks it really felt like someone had given me my life back, no more pain at all. plus the bonus of no more periods to worry about. You need to talk to your doctor about all your options and take time to make an informed decision. But leaving the cyst in is not a good idea, as this is also the kind of thing cancer likes to attack. Why give it that option? Good luck. Hope you feel an awful lot better very soon. :o)
