5mg tamoxifen



New here, just finished 2 surgeries and 15 radiation treatments dcis gr 1-2 Er/pr+ her2 neg. I am 65 Just going to start 5mg tamoxifen next Monday Apr 22. Hesitant when they did the pathology on my sample which was very small I had a slight break in one of the Ducts so that changed me to invasive but it was microscopic so my oncologist said 5 mg is fine with him because he has studies showing 5 mg works just as well . He said 3 yrs on it .I want my pap done orior to starting this as its been 2yrs.I live in canada.

    Hi @sue380. Welcome! I’m sorry you need to be here though. But I’m glad you found us and feel comfortable posting. I’m currently taking 20mg of Tamoxifen, and I’m pre-menopausal, so probably no real help to you, we’re apples to oranges :) but I wanted to still say hello.

    You said two surgeries … was that to get better clean margins? It sounds like it was found and removed at just the right time! Phew! How are you feeling? It’s such a whirlwind of appointments and information and decisions. I haven’t researched about 5mg Tamoxifen, but would be interested to know the studies. I’ll have to look it up. Are you feeling good about the proposed treatment?

    Thank you for saying hello. I had two surgeries because after the first lumpectomy they found some invasive cancer which was microscopic so I had to have a second surgery to check my Sentinel nodes. They only had to remove one and it was clear of cancer. I am very apprehensive about taking tamoxifen but hoping 5 mg does not give me bad side effects as I have fibromyalgia and I'm very sensitive to any medication. I was on HRT for 10 years so currently I am experiencing horrible hot flashes since I had to go off it last October and just generally feeling unwell.
