Vikki Jones is undergoing surgery to remove both her breasts at the age of 32 - even though there is nothing wrong with them.
Doctors have told her she is at very high risk of getting breast cancer at some point in the future, so she is having them removed to protect her from the disease.
Vikki is keeping a web diary of her operation and hospital stay for BBC News Online.
Friday:: Thoughts of home :: 0900 GMT
I don't know how long they are going to keep me in for.
They did say that I would be able to go home on Friday, but now they think it might be next Tuesday or Wednesday, which is fine by me.
I am enjoying the rest and watching day time television!
The dent in my breast has gone down, which is good and one of my friends came to have a look at my boobs and she said that they looked quite normal.
I am feeling a bit better now. I didn't eat much yesterday, but I am hoping to make up for it today, even though I do have some ulcers in my mouth.
I don't really want the children climbing all over me, although I am looking forward to seeing them soon. Milly has been in, but Tate is only two-and-a-half so I don't think I will be seeing him until I go home.
I want him to know that when I see him, I'm back for good.
Thursday:: Feeling down :: 0900 GMT
I finally got a good night's sleep - thanks to the temazepam. I slept in the same position last night though and I was a bit sore. I was in a lot of pain.
I was a bit upset when I got up this morning about my boobs and I the surgeon came to reassure me that they would be alright when I was wearing a bra - so I'll have to start wearing one.
I have been feeling a bit sorry for myself. I had been thinking I was doing better than I was and I think the emotion of the whole thing is just starting to hit me.
I've had a bit of a cry and I am not doing so well today. I haven't felt up to visitors, but I have had some more morphine and hopefully will feel better soon.
Wednesday:: Doctors pleased :: 1500 GMT
I am really looking forward to having a bath. I have a friend coming in to do my hair and then I am going to do my make-up which will make me feel a bit better.
I am starting to feel really sore and my boobs feel as if I have been in a car crash. It is like the seatbelt has been stretched and pulled across them.
I am glad the operation is all over, but I really need to sleep. I am going to make the most of being able to rest. The doctors say they are pleased with my progress and I really want to go home at the weekend.
Wednesday:: Weird shape :: 0900 GMT
I had a smoked salmon and cream cheese bagel this morning that my friend brought in.
I have had another look at my boobs and they are still looking misshapen and horrible.
The doctor said they will not look like normal though for a couple of months.
I had asked for some underwear vouchers for my birthday the other week, so that when I knew the size and shape my boobs were going to be I could choose some new bras.
But looking at them now I don't think they are going to be the right size for any bra.
They have not settled down yet, but the doctor says they will.
Wednesday:: Early morning :: 0400 GMT They have taken my drips out so I am able to get up for the first time.
I can move around, which is good. I am hoping to go home at the weekend and they said the sooner I got up and around the more likely I would be able to get home quickly.
I haven't had much sleep though because the hospital is really noisy so I am being woken up about every half an hour and I am really getting a bit tired.
Tuesday:: Out of it :: evening I feel really out of it. I am on morphine and that is keeping me from feeling pain. I can't really remember anything that has happened. I am just out of it.
Tuesday:: Not bad looking :: 1545GMT
I have just taken a peep at my new breasts and they look fine.
I was pleasantly surprised when I saw them. Haven't got any bandages except where the scars are, but there does seem to be a dent in left breast so I am waiting for the consultant to come up and explain to me what that is all about.
But I do feel surprisingly fine, although I still have my morphine. I am managing to eat a sandwich, which is good, but I still feel a bit rough.
Tuesday:: Back, but sore :: 1500GMT
I have just come back from the theatre and I feel totally out of it. I have got four drains into my chest - lovely.
I have a nice little morphine pump and I don't feel any pain. I was about six hours in theatre and that was much longer than I expected.
Nobody has told me why it took so long, but I expect they will tell me soon. My family were surprised I was so long.
I was worried about the anaesthetic and they didn't give me a pre-med to calm me down. But the anaesthetist was lovely.
He made some jokes with me and he told me to imagine that I was somewhere nice. I told him that I would imagine that I was in Ibiza.
I'm about to look at them - I'll let you know what I think.
Tuesday:: Ready to go :: 0810GMT
They are wheeling me down in about 10 minutes for my operation and I do feel surprisingly calm.
They haven't given me my pre-med though and I am totally conscious. I've just had a last look at my breasts, but I still don't feel worried about what I'm about to do.
They have told me that the operation is going to be about two and a half hours.
Time to go now - the trolley has just turned up to wheel me downstairs. See you later on.
Monday:: St Thomas' Hospital :: 2200GMT
I have arrived at the hospital and I feel surprisingly calm.
I am a bit nervous about the anaesthetic and about my stay in the hospital because I worry about picking up an infection. But I just want it over with. I am fine.
I did want someone to film me coming out of the anaesthetic though so that I knew what I looked like when I did because I am curious about that.
I got a friend to photograph my breasts before the operation and am going to get her to do it after I have had reconstructive surgery as well.
I am going to sleep on my front tonight though to make the most of my still having my breasts.
