Had mod.cervical displasia removed about 10 years ago with laser ablation surgery. normal paps before and after. had hpv tests past 5 years and they have always been negative. chances for displasia to reoccur? can stress/poor sleep make it return

CIN aka Dysplasia: No, "CIN" isn't how you contracted the HPV virus that causes the dysplasia, rather it is the alternate name for the same as Cervical Intraepithelial Neoplasia(CIN). Yes, it can recur if re-exposed or the laser ablation did not go deep enough under the surface epithelium which is unlikely since you have been disease free X 10 years.

Yes it may return if: The only way to have dysplasia reoccur is if you become exposed to the HPV virus. Cervical dysplasia is caused by sexually transmitted HPV virus. Once you are treated and paps are normal and HPV tests are normal, then you cannot develop cervical dysplasia unless a new exposure occurs. Using condoms will prevent this. Stress or fatigue cannot make it return unless HPV is already present
