Anyone borderline estrogen +?

I am her2 + and borderline estrogen + (11%). I am premenopausal and 36. I am trying to do research and decide if tamoxifen is right for me. I have weekly herceptin infusions. I am just wondering if anyone has a borderline estrogen value like me and what their doctor may be recommending. Thanks to all! (Sorry-didn't have time to register.) (oh, and progesterone is negative.)
