Hello and welcome to this forum. We're glad to have you here with us.
Cervical cancer is not a common outcome of HPV, and can be prevented in virtually all cases by having regular Pap tests and, when needed, treatment and follow up exams. It sounds from your post as if you're doing everything recommended by your healthcare provider.
Cervical cell changes associated with HPV do recur in some cases, but by no means all. When they do recur, they show varying degrees of persistence. Some people may experience only one episode, while others may experience several. However, most people's immune systems, with time, seem to gain control over HPV, making recurrences less frequent and usually eliminating them eventually.
On some other discussion threads here we've talked about how partners who share the virus probably don't have to worry about reinfecting one another. Read more at http://www.ashastd.org/phpBB/viewtopic.php?t=208
Interferon is not commonly used with HPV related lesions, primarily due to cost, side effects, and the availability of other treatments that are effective. When interferon is used following HPV diagnosis, it's more often done with lesions (like external warts) than with cervical cell changes. Ask you healthcare provider if you have questions regarding treatment options.
When someone is first diagnosed with HPV, it can be very difficult on a person's self-image. These emotions of guilt and shame often stem from the fact that we grow up with a lot of misconceptions about STDs, such as who gets them and why. In reality, an HPV diagnosis does not reveal anything about a person's values, their personality, or choices, only that they like many others, have contracted a common virus. You are taking an important step by educating yourself about HPV.
