I had breast cancer in 2018 which was treated by surgery, radiotherapy and 5 years of tamoxifen which I finished Sept 2023. I was diagnosed with an undifferentiated connective tissue disease in 2021 which my rheumatologist is certain was caused by my breast cancer treatment and hormonal changes (menopause) caused by tamoxifen. Earlier this year I had a short bleed which I thought was my body trying to return to pre-menopause as my oncologist said there was a chance this could happen. I saw my GP who referred me for tests and after a few months of various tests I have been told I have endometrial hyperplasia which is a side-effect of tamoxifen and caused by oestrogen. I am being listed for a total hysterectomy in January as if left, these cells will turn cancerous. I feel angry that I am still suffering side effects of the treatment for breast cancer, but I am also worried because my breast cancer was oestrogen receptive, so if my body is producing oestrogen again, does this mean I am at a higher risk of my breast cancer returning. I dont know who to turn to for advice and reassurance and I feel like I am going through all the emotions of cancer treatment again.
