Hello Tulah, 

A warm welcome to Cancer Chat. I am sorry to hear about your daughter's diagnosis and about the difficult treatment choices she has been facing. Our website has useful information on treatment for breast cancer which you are welcome to have a look at and in particular there is a section there on targeted and immunotherapy drugs for breast cancer which may be of interest to you. 

I hope that you will hear from other forum members who have gone down the same route and that they will be along shortly to share their experience with you - although as mentioned in our terms and conditions we do not allow specific consultants or healthcare providers to be named explicitly on the forum. 

Feel free also to talk things through with our cancer nurses and you can get in touch with them on this free number 0808 800 4040 - their line is open Monday to Friday from 9am to 5pm. 

I hope your daughter finds the best possible treatment and that it is successful and works well for her. 

Best wishes, 

Lucie, Cancer Chat Moderator
