If there's still a cervix, we need paps done and an evaluation of the vaginal walls etc. as well as a pelvic exam. Even though not sexually active, if there's a cervix and given your history....there's still need for paps. You may not need them every year anymore...perhaps, every 2 or 3 but, you still need them.
I'd be heading to another doc for them or, simply demand that he do them anyways....."for your peace of mind" if that's what he'll accept.
I had a partial hysterectomy in which they took my cervix and uterus. My doctor is very thorough, and he explained that I still need to come in for a pap smear since one could get cancer of the vaginal wall. I feel better knowing that all is okay in that department.
