Bleeding from tamoxifen

2 May, 2006


I had my ovaries removed 3 years ago because I have the BRCA11 gene.

I take tamoxifen prophylactically to prevent breast cancer, etc. I developed one of the complications from taking tamoxifen which is build up of the lining of the uterus and developed light bleeding. I had a hysteroscopy and d & c this past weekend to address the problem. I am bleeding lightly as if I am having a light period. What is my status?

I just want to tell you how much I appreciate this service. This is obviously very personal and I would not feel comfortable talking to my Rabbi about this. So, thank you so much!


We’re glad to be of help.

The bleeding from your uterus, even if caused by tamoxifen and not by your ovaries, rendered you a niddah. Therefore, from what we understand, you were niddah prior to the procedure.  So long as five days have elapsed from the onset of bleeding, you may perform a hefsek taharah as soon as your bleeding stops, which may take a number of days. If you have difficulty achieving clean bedikot during the shivah neki’im, please contact us about the possibility of reducing the number required this cycle.

Refuah sheleimah!
