Thank you for posting. It is understandable that you have questions about what to expect when you stop taking tamoxifen. Many people contact us unsure if the side effects they experience when their treatment ends are normal.
Tamoxifen blocks the effects of oestrogen on breast cancer cells that may be in the breast or anywhere in the body and can cause menopausal side effects such as joint pain and difficulty concentrating whilst taking it. The side effects after stopping tamoxifen can vary from person to person and will usually lesson over time. The symptoms you describe do sound hormonal in nature. Generally, periods will start to stabilise after a few months of stopping tamoxifen if someone has not already gone through the menopause naturally while taking the drug. This would be more likely to happen the nearer someone is to the age when menopause naturally occurs.
As you are concerned, it may help to talk to your treatment team or GP about this and the joint pain you have been experiencing. They may be able to check your hormone levels.
Talking to someone who has had a similar experience can often be helpful. Our Someone Like Me service can match you with a trained volunteer who’s had a similar experience to you. You can be in touch with your volunteer by phone or email and they can share their personal experiences to answer your questions, offer support or simply listen to how you are feeling.
You can ring the Someone Like Me team on 0114 263 6490 or email them at email@example.com, so they can then match you to your volunteer.
We also offer face to face and online Younger Women Together support events which are designed specifically for younger women (20-45 years) with breast cancer.
