Wait! I had the same issue 15 years ago and was able to shift it with diet.
I took a folic acid supplement and did some visualization (releasing anger against previous sexual partners who didn't respect me). Two months later, my Pap smear was normal.
I suggest liver as a great source of bio-available folate--many people aren't able to convert folic acid to folate efficiently. 4 oz. 2 x a week.
If you can't handle liver, there is a bio-available folate supplement out there. Google it or bug me!
I would also supplement Vitamin D3 if you aren't already. I'd be aggressive and do 10,000 IUs/day for a couple of months & then test my levels and adjust. Take some Magnesium Glycinate before bed 200-600 mg to help with sleep & make your D work properly.
I wouldn't go ketogenic, since it isn't full-blown cancer. You want to reduce your stress as much as possible, for sure.
ETA: Some studies on PubMed do not show any effect from folic acid supplementation, but this one did:http://www.ncbi.nlm.nih.gov/pubmed/7064879
