I too was told i had low grade changes and also HPV
From what I understand , most women get this at some point but HPV is a sexually transmitted infection which in some cases , in mine anyway , HPV virus can be responsible for abnormal changes . Mine was classed a high risk HPV - was pretty gutted to say the least as had been with my partner for 4 years :-( most women clear the virus without knowing they have it others like me had to have further treatment which in my case was a LLETZ procedure . To remove the abnormal cells and area .my consultant is hopeful that this will then get rid of it and encourage new cells to form . Had this done 2 weeks ago am now waiting for final results
Hope this helps you a bit as I was upset and confused too .
