Thanks for your post. It’s understandable that you want more information and to find out whether bleeding while on tamoxifen would be investigated.
You don’t mention how long you have been on tamoxifen, and if you are pre or post-menopausal. However, if you have any unexpected vaginal bleeding or pain while on tamoxifen, this would usually be investigated, and your treatment team may refer you to a gynaecologist. This is because tamoxifen can affect the lining of the womb (uterus), called the endometrium, which may become thickened.
We would suggest contacting your breast care nurse or treatment team again about this. You can also contact your GP as they can refer you to a gynaecologist for further investigations, if needed.
Do call our Helpline if you would like to talk this through or have any further questions. Your call will be confidential, and the number is free from UK landlines and all mobile networks.

I don’t have any great wisdom but wanted to say I was also told to contact my doctor if I started bleeding whilst taking tamoxifen.
wishing you all the best
One of the last things my oncologist said to me was to contact him urgently if I started bleeding on tamoxifen. I’ve been bleeding on and off over the last few days but was unable to get hold of him by phone, eventually sent his secretary an email which she responded to saying ‘ just carry on taking tamoxifen and we will send you a blood form to check levels’. I thought all bleeding whilst on tamoxifen needed to be checked? I’m not overly impressed with my oncologist anyway and I’ve sort of been cast aside and haven’t been given any information about what’s happening going forward. Is it normal for them not to investigate this?
