Tonya,
I believe that the surgical decisions should definitely be your personal choices.
My experience: My physicians told me that having masectomies would not lengthen my survival; however, I wanted to try to be symetrical (concave of both sides) and my gut told me it would lessen my risk of cancer recurrence in the breast. After my mastestomies, the pathology revealed more cancer than originally diagnosed. It was found on the cancer side, and in situ (pre-cancer) was found on the opposite breast. I was very disheartened to learn that I had quite a bit more cancer than initially diagnosed, but then it did confirm that I had made the best decision for me.
It's good that you are taking the time time to learn and assess all of your options and to hear others' personal experiences. I know you will make the best decision for you!

My best wellness
wishes and
prayers for you!
And I
hope you have a
good experience and
great response with Navelbine.
And Enjoy some coffee

!
