tomox question??

I have a question about Tomox. I wrote on this back in march I think. I had breast reduction surgery at the end of jan (love it) and found out that i had LCIS as a result from tissue biopsy. They then checked many other areas in the tissue and it was only in 1 spot thankfully. I am estrogen positive, 47 years old, pre-menopausal and have 3 kids under the age of 13. After many consults with Oncologists and b surgeon I thought I was going to go on Tomox, but I can't bring myself to do it. I am so worried about SE's and how it will affect me and then I worry about the risk of stroke etc. I have an appt for my 6 month mammo at the end of June, I am sure he will want to talk more about it then. This is what I am wondering - if I were to have an oophrectomy/hysterectomy would removing that estrogen be sufficient or really is that still not enough?? i sure people have done this and still are on Tomox but i am just trying to figure out the best route to take. I thought I was handling this whole thing pretty well but taking this med just freaks me out. I know I probably should just try it and see but i started thinking more about these other ways of removing some of estrogen. Can anyone give me advice on this? Thanks ahead of time. I found this site soon after diagnosis and was soo happy - everyone here seems sooooo supportive!!!!! I also put this post on the hormone treatment section as well. Now obviously I realize that taking this med and dealing with possible SE is better than BC, but i am still just so worried.
