I had a hysterectomy complete, ovaries and cervix, at age 42 because of many menstrual problems. If you are not a smoker you might consider taking a low dose estrogen therapy which is what I did and might ward off a relapse. For me it wasn't a cancer risk but they did test the tissue to make sure it wasn't present.

It sounds like your doctor is on top of things and being proactive for your benefit. Hysterectomy is not major surgery but make sure you rest enough in your recovery.
