Keep in mind that if ONLY the uterus is removed (and not the ovaries) you will not go into instant menopause. It is the ovaries that produce hormones and if they remain they will continue to produce hormones until they would gradually slow and stop with aging normally.
Thus, you can discuss only removal of the uterus (if you wish) for removal of the fibroids while retaining your ovaries.
For what it's worth, I had a hysterectomy at age 47 but retained my ovaries and did not begin menopause until my late 50's.
We can't tell you if breast surgery is really necessary now. This is something you need to discuss with your physician but ultimately the decision would be up to you as to whether a 1 percent chance of problems in the future warrants surgical intervention.
