Persistent integrated HPV

Hi this is my first time posting. I found out last year that I was carrying HPV but my Pap smear was normal.

I recently had a Pap smear done which indicated that abnormal cells were present. I also tested positive for HPV (other). I think this means that the subtype of HPV is unknown.

Upon further testing I was told that the HPV had integrated into my DNA as well.  I have been married for over a decade so I must have been carrying this virus for all these years.

It scares me that the virus has integrated and has persisted for so long. 

Has anyone experienced anything similar? I'm booked for a colcoscopy next week. This is all very new and frightening to me.
