Hello sun56 and thanks for posting, 

I'm afraid I can't explain what has happened or answer your question properly because I don't know what was seen on your scans or why a biopsy wasn't done. I think you need to talk to the NHS breast clinic to ask why a biopsy was asked for but never taken.  Or your GP might be able to help - the GP can take a look at their information from the breast clinic about the outcome of your appointment.  Do get in touch with one or both or them and see what they can tell you. 

I hope you can easily get this sorted out and that everything turns out alright.

Best wishes,

Julia
