Yes some forms of hpv can progress pretty quickly unfortunately - it's terrific that your daughter's medical providers are on the ball with this and being fairly aggressive about it even if they have been seemingly oblivious to the whole hpv part of it all. With moderate dysplasia - the LEEP is probably a good idea. Better to be too aggressive than to sit back and let it have more time to do what it wants to do at her age. If you want to know if indeed she has hpv and if so what type - they can do a hpv dna test before they do the LEEP. a regular pap test doesn't check for hpv. The thin prep brand pap tests do - they report back if high risk hpv is found or not. I'm guessing your daughter had a regular pap test since there seems not to be any idea of if she definitely has hpv or not. Did they explain the LEEP to you both? Basically they look for any suspicious areas on her cervix and then remove them. They take as little tissue as possible in order to preserve her future fertility.
As far as std's - it was pretty close to the 3 month mark for her testing - negative results should be accurate for hiv. was she also tested for herpes? The reason I ask is that most clinics don't test routinely for herpes so it's always a good idea to make sure she was. There is a terrific list on ashastd.org of what std's to get tested for.
Unfortunately condoms are not always used properly and they aren't 100% protection for either herpes or hpv. A recent study did show that if the condom was put on from the time the pants come off it reduced the chances of transmitting hpv significantly - the odds of protection go much lower if you wait until actual penetration to apply the condom. Most people do a lot of "fooling around" naked before the condom goes on so yes indeed you can still get herpes or hpv even if you use a condom everytime ( and even if you are still technically a virgin too even ). Since this would be a type of herpes that in a male wouldn't present with any symptoms - chances are good that her bf had no idea he even had it. There isn't a commercially available test for hpv in males at this time.
You can check out www.pubmed.gov
for the latest info on follic acid and hpv infections. Also you can check out www.clinicaltrials.gov
to see if any hpv research is going on near you that your daughter might be interested in participating in. There are some terrific studies going on right now that might be worthwhile to check out. most of them are in phase 3 testing which is the safest stage.
I'm really glad you are there with your daughter for all this
So many times on the boards daughters are afraid of what their parents would think of them so they try to handle this all on their own. Kudos for you for being there for her and helping her with all this
