I know exactly how you feel
I'm 26 and I've had CIN III 3 times now in less then a year and a half.
I've had laser treatment (Aug 2006),LEEP (July 2007) and now probably another LEEP, I can't even count how many times I've had biopsies probably over 10 times. I'm stressed out beyond belief. I have also been in pain down there just really sore. Though my doc says it ha nothing to do with it.
Though I will share a conversation I had with my family doctor when he got the last results back. He wanted to clarify really what would happen if I chose to have a child. He said one of two things COULD happen (unlikely chances are less than 20%) that could affect my fertility. One the cervix could lose its elasticity and seize up and build up of scar tissue from treatments and I would have to have a c-section. He also said very very very rarely the cervix can inhibit the sperm from getting past the cervix because of the scar tissue getting in the way. He said it is so rare though. The other thing that "could" happen is the the cervix becomes weak from damage and possibility of miscarriage but this can be easily fixed by placing a stitch in the cervix at the beginning of conception and removed after 4 months or so. My doctor said that my gyno/specialist would know exactly what I would be more of a risk of. He reassured me that if I did want kids I would likely have no problems even with all my treatments and if I did it could be dealt with.
The Gyno who had done the biopsy recommended another LEEP with the latest results. Since I stated I just want this over with my doc is recommending back to the gyno that I should have a cone biopsy since it has the lowest rate of reoccurence and honestly I just want this over with. My doc did warn that a cone does make the cervix very weak and I williprobably need a stitch in my cervix when I concieve but it won't be a problem.
Hope this helps everyone.. I still have to talk to my gyno about this.
This is just so stressful and scary.
