there have been a few studies that do indeed indicate that the presence of HPV after treatment can increase the chances of recurrence but again these studies are very outdated and there are other studies that say that about 45% of women who have had treatment for locally advanced cancer of the cervix still have persistent HPV. which in any case tells you that if this is a huge factor then the cure rate would not be as high as it is.
So, I would not worry about that factor as it seems there is not enough solid evidence to trully indicate anything other then they will keep a very close eye on you.
Now, in ways you are lucky because you found this info out and most places do not test for this as a mandatory thing as it is not supported by the world health organization which sets forth the treatment and planning and post care of patients. Most governments go strictly by what the WHO sets out, you however are in the US and they seem to investigate a bit more beyond the recommendations especially if you have good health care. So what does this mean for you.... it means you should be keeping to a strict regime of making sure your body has what it needs to fight off the HPV, like taking vitamin B12 and folic acid and vitamin E. I would strong suggest you seek the help of a specialist in supplement care and get a plan in place to fight this HPV to insure it will not cause your cancer to come back. Find out exactly what strain of HPV you carry and take this info with you as this will help the natural Pathic dr to really set out a plan geared just for you. There are many ways they can flush your body with a session of iv fluids that contain what you need. It can be pricey but it's well worth it.
Do try not to worry so much but turn this info into a positive thing and these treatments will also help your body recover and help prevent long term effects from the radiation and chemo.
Chin up! it just means you got some knowledge that most of us would not unless we seeked it out ourselves.
