Hello ma am. Yours is indeed a complicated case. As you have been diagnosed with breast cancer, your hormone levels will most certainly have to be closely monitored. I also hope you have sucessfully completed your family. A hysterectomy at such an early age will cause a few complications, like early aging, drop in libido, etc. Complications which would have been acceptable at a later age, but would be a little difficult to accept at such a young and tender age. I would recommend going ahead with the hysterectomy, but close and regular monitoring of your hormone levels. A balance is very important. Hope this helps. Take care.
