Hi there symonds and thank you for your post

I am sorry but I am unsure what rairema 7 is, I haven't heard if this before.

If you can come back with more information we may be able to help your further. If you don't have anything else I suggest speaking with the doctors involved to explain this further.

There are many different types of breast cancer that we have more information about on our website. As you say some breast cancers are hormone driven by oestrogen but I am unfamiliar with the term rairmera 7 or what this may mean. 

I am sorry we cannot be of more help on this occasion Please get back to us if you need any more information or support.  You may find it helpful to talk things through with one of the nurses on our helpline.  The number to call is Freephone 0808 800 4040 and the lines are open from 9am till 5pm Monday to Friday.

Best wishes

Naomi
