This is a really hard question to answer and I can not imagine having to make the decision because of cancer running in my family. I did have a complete hysterectomy because of severe endometriosis. I wish I would have had another choice but when I had it done I tried the only treatment available and it failed.
Will you be have a complete hysterectomy? If so, and cancer runs in your family your Dr may not let you take hormone therapy. You can have sweating, mood swings, little interest in sex, vaginal dryness. If your Dr does not want you to take hormones you should be able to take Black Cohosh. It really helps with the symptoms after having the surgery. It can be bought over the counter so you can buy it at almost any drug store.
If I can answer any more questions about your surgery please let me know.
