I’m not sure it was because of the tamoxifen or not but due to the abnormal bleeding they did a transvaginal ultrasound and I had a uterine fibroid and a large cyst on my ovary and with the abnormal bleeding, they thought it was a good idea to do the hysterectomy since they couldn’t put me on birth control to see if that would help, due to the breast cancer.
When they biopsied everything afterwards, it showed I also had endometriosis and adenomyosis. So it was definitely good I had it done. But, my gyno did say that any abnormal bleeding while on Tamoxifen calls for a transvaginal ultrasound. So watch for that.
