Two weeks off Tamoxifen after 10 years

Hello my name is Birdy, I am 63 and I was diagnosed with ER + breast cancer in my right breast 10 years ago. I had a lumpectomy and then I took part in the Import High radiotherapy trial and as a consequence of that was seen annually at our local centre, with my last visit in April this year, 2024. I was given the higher dose of targeted radiotherapy. Since that time I was on Tamoxifen. At my last visit the consultant told me to come off Tamoxifen. It has been two weeks and yesterday I woke up with a flat red non-itchy rash over my affected breast, particularly over the site of the lumpectomy. This rash has not appeared anywhere else. I’m really worried and would appreciate any advice or information.

Hello birdy61

Thank you for posting about the non-itchy rash on your breast.

This could happen for a number of reasons and is unlikely due to you stopping tamoxifen two weeks ago.
