An HPV diagnosis can be very confusing.
How did your doctor diagnose the HPV? Have you had a colposcopy and/or ECC (endocervical curettage)? I would think you'd have had a colpo before the doctor recommended a LEEP, but I don't know for sure.
The LEEP removes a cone shaped piece of the cervix and it cauterizes the edges of the "cut" (biopsied tissue and intact cervix) to reduce bleeding. The piece that is removed is then sent to a pathologist. He/she will look for abdnormal tissue and identify what type (if any is found).
Sometimes the LEEP is diagnostic AND treatment, meaning that no furher treatment is needed after the LEEP (except being vigilant about getting followup appointments for ever). Other times, the LEEP is simply diagnostic and can indicate the need for further treatment.
Sometimes the LEEP can compromise the cervix's ability to maintain a pregnancy. In that case, there is a procedure (circlet?) to keep the cervix closed to allow the baby more time to develop. I believe if that procedure is done, then the baby is delivered by caesarian section.
You asked if the virus will "come back". That is difficult to answer. Your body will always have evidence that you have had HPV. There is some discussion as to whether the body can fight off the virus so it never causes further problems. The other side of the discussion is that the virus can fought, but can be reactivated later. Researchers haven't determined definitavely which happens. And, just because the atypical cells are removed in the cervix doesn't mean the virus isn't doing damage elsewhere.
What should I do? Have the LEEP, try for a baby, then carry on with 6 month check ups? Is there anything else I can take to help our situation? Should I take the LEEP or is this a bad thing?
I can't answer those questions. You need to address those with your doctor. You can call and see if you get the answers you need, or make another appointment with the doctor so he/she can explain things to you. After my doctor gave me the diagnosis of positive for high risk HPV, I scheduled another appointment with her because I had so many questions I wanted an answer to.
When you call or go back to your doctor, I highly suggest you go with a written list of questions. That way you "remember" to ask everything you wanted to ask, and you can write his/her answers. It is so easy to forget things, especially when dealing with a stressful situation.
I hope that helps a bit!
