Off Tamoxifen and pre-menopausal

[mts]

I am 2 1/2 yrs out from original Dx of DCIS with some invasion- had lumpectomy, 0 nodes, AC+T+H for a yr, rads and tamox since the radiation... I was only 10%-15% ER positive and PR negative. My onc said OK to taking me off the tamoxifen. I am still pre-menopausal, so no other hormonal is being provided to me. He prefers me to go into menopause "naturally". I personally am relieved to getting off of it, but wonder if anyone else has removed Tamoxifen from their treatment protocol and substituted it for anything else -or nothing at all. I understand that being 10%- 15% ER+ is barely skimming the advantages of taking tamoxifen... skimming is better than nothing, but at this point, does it realy matter ?
