Referring and changes

Does anybody have any idea why they refer for low grade changes and HPV high risk.
I thought they only reffered for medium to high grade changes.

Hi @Patty i think its because HPV creates,the changes if you get me so they will have,a closer look at it through a colopscopy app try not to worry or overthink it its procedure to do that when HPV is present if there was just HPV an no changes i think they just monitor it xx

Thank you xx
