Hello dear, I perfectly understand your situation, I turned 32 years old and I have a 1 year old baby (Gaspar turns 1 year yesterday!! I am sooo happy!) I am also estrogen positive, not really high just 30% do you know your percentage? I talk to one of my doctors and if you are below 25% you probably WILL NOT benefit much from tamoxifen, you can also chose to have it for only 1 or 2 years and then try for babies, I have been doing science for over 10 years and I have many papers that can help you to take the decision. I would like to say that I had cancer before getting pregnant (of course as Merylee and others the doctors didnt think the lump on my breast was something to concer about it!) so I felt the lump around Dec 2009 Jan 2010 and got pregnant later in March 2010, I had a beautiful pregnancy, a wonderful and easy waterbirth and I asked again the doctors about my lump (which got bigger) around March 2011, in May 2011 after a core biopsy I was diagnose with early breast cancer, so my point is PREGNANCY DOESNT TRIGGER CANCER OR WORST YOUR PROGNOSIS, I am not telling you this just because my own experience, but after reading many medical papers and taking to my oncologist. If you or another of you guys wants me to send you some of these papers to read a bit please let me know and I can send them to you because I dont know how to attach them here! ha! Send me a text as I am not cheking Internet very often (my mobile is 0411836970).....ALL THE BEST TO YOU AND KEEP SMILING!!!
Leonor
