Thank you for taking the time to write. I believe that there is a database - the surgeon can put all your data into that (eg age, size of lump, type of lump whether it be hormone related, whether you have had mastectomy, whether it was present in lymph node)… lots of different information. Results were within seconds. They are percentages of survival rates comparing different treatments and effectiveness. If I didn’t have mastectomy I would more than likely be required to take Tamoxifen. But I’m wondering if it’s worth it for that 1%. I guess I do need to listen to my heart. I have sat down with GP since this post and gone through potential side effects from Tamoxifen and we decided that I wouldn’t take it.. no onespecific reason. But it is definitely on my mind!
