New member question on HPV related cancers

Hi was wondering if anyone can shed light on the other HPV cancers ? I had treatment for a small area of CIN 3 on cervix 6 months ago but I'm worried about the affect of the HPV on my body like all my previous smears have been clear but this one wasn't and now I'm left thinking but what if I have pre cancer in my anal/ vulva or vagina also? Is there any tests/ screenings, that can be done to check for this? and if not on the NHS would private do any of these tests?
