Hi
I had IDC and high grade DCIS which were ER+. I was advised a small amount of alcohol was ok. Sorry I can not remember the exact recommendation (one glass of wine a week or similar).
But I have stopped drinking altogether as there is research which shows, and explains how alcohol has an effect on Estrogen, which then reduces the effectiveness of hormone therapy. This was an important factor to me. I understand you’re not taking hormone therapy, but my thinking would be reduce the odds of it coming back.
Its personal choice, and there are many on here that continue to drink because its there bit of normal and joy, and let’s be honest, when going through cancer treatment you sometimes crave for something normal!
Perhaps make some enquiries with your health team to satisfy your own mind. Cheers x
