I have read a lot now and the benefit does not outweigh the risks involved especially as I am ER negative and had no lymph node involvement. There is a lot of valuable information on the internet regarding the initial trial and articles in the medical journals. I will still do some more research but probably will not go on the trial as the literature, in my particular diagnosis, suggests it is not worth it. The 'survival increase" was only on a two year post trial as it is too recent to have a five year statistic. Thank you all again
