Your doctor is right, a hysterectomy is not a cure for HPV. However, when a woman continues to have ongoing problems with abnormal cells on her cervix, sometimes there is little other choice than to have a hysterectomy.
You commented that you've had several biopsies, a cone, etc. I assume that means you've had abnormal cells noted on a PAP or biopsy. Do you know if they obtained clean margins on your cone? Have you had a PAP since your cone was completed?
HPV is a very common virus. It is estimated that 80% of sexually active women are exposed to it by the time they turn age 50. The vast majority of these women never even know they've had HPV--most fight off the virus before any abnormal cells are ever detected. And most women who have had HPV will fight off the infection on their own within 2 years of acquiring it. That leaves only a very small percentage of women who have ongoing problems enough to require treatment with a hysterectomy.
As stated previously, HPV is not cured with a hysterectomy. Once you've had HPV you always have it. Most women are able to keep it in a dormant state where it can't cause any problems. However, it is essential even after a hysterectomy that regular PAP's are completed to determine if there is any recurrence on the vaginal walls. It can also present itself on the vulva, so self-exams are also important. When caught early, dysplasia is very easily treated.
Good luck at your 6-month checkup! Hopefully your PAP will come back normal at that time!
