She does not have cancer, but does have a family history of the disease.
Vikki, who has been sharing her thoughts with BBC News Online in the form of a diary is now back home and starting to rebuild her life.

I got home on Sunday. I was hoping to stay in a little longer, but they needed my bed.
I am just spending my time at home now watching the television and recuperating. It is nice to have the time to relax.
I have six weeks of recuperation to look forward to and if I am feeling as well as I am now I will feel really great by the end of it.
Recovery
It will be nice to have Christmas off work and it will give me time to unpack my stuff as I have just moved house and everything is still packed up in boxes.
But it is driving me mad not being able to get out.
 | I have no regrets about having the operation  |
I am not really scared about going out, but I must admit that when I went into a DIY store the other day I started to panic because I was worried about people bumping into me and I had to come back.
I am still a bit sore and I can't pick the kids up, but I am starting to recover well.
The mornings are the worst because that is when the breasts are most painful, but I think I am beginning to get my pain relief under control now so it is a lot better.
My boobs look alright. One of them is still a bit square, but I don't think they will be able to tell what they are finally going to look like for about another two to three months.
They are a bit sore, but they are moving about a lot more now and I am not displeased by the results of the operation. I will just have to wait and see what it all looks like when I have the stitches out.
I have no regrets about having the operation.
Children
My son Tate did not talk to me for a while when I got back because he thought I had abandoned him, but I suppose that is understandable as he is only a toddler.
Now that I am starting to feel better I am looking forward to getting more healthy.
I am going to continue on my low dairy diet and I can't wait to go back to the gym and start exercising again.
I haven't had a cigarette since before the operation and I am hoping to keep that up. I have wanted to have one, but so far have resisted.
I think I will try hypnotherapy and see if I can manage to give up smoking for good.
"I haven't even had much to drink. I did have one glass of wine though and that was when I wanted my cigarette.
I am just looking forward to the future now.
I feel it is a relief to have the operation all done with.
I do not really feel any different, although I am aware that it could have all turned out very different.
My surgeon said I was really lucky because my nipples were in a line and that had made things much easier.
He is very pleased with my progress."
