Hi,
I think its pretty natural to be a little anxious in a situation like yours. But usually there is ano cause to worry as the doctor may have something else on the mind than a breast cancer report. There are many reasons why a doctor may ask you to come in. Perhaps the doctor noticed anxiety and has called you in to dispel your fear. on the other hand, since not much history on your case seems to be available, there could be some other significant reason in the report which he may like to discuss. Stay confident and dont worry too much about it. Your doctor cares for you and I am sure he would help you in the best possible way.
Please let us know if you have any queries after your visit.
Good luck.
100 to 1 it's just a normal post-op visit which happens to coincide with the pathology report.
