Your choice is certainly your own, and there are so many factors to consider. Do you have/want children? Do you have risks for cancer? Is the quality of life you have now what you want to continue with for the next x years until you reach menopause?
No one can make the decision for you, but you can certainly do lots of research on the web. If you have not been to hystersisters.Com I would recommend it for support and guidance. I love it.
Good luck to you no matter which path you choose.
