I am sorry, it is impossible to comment on these questions without physically examining the patient and going through all the reports in detail. Decisions in cancer treatment cannot be done by reading a few lines of text which you have mentioned above. It takes 20 minutes to half an hour for us to assess a patient in detail including reports. Any form of medical advice is absolutely beyond the scope of this forum. I can only tell, that if you are not fully satisfied with your doctor's decision, you can take a second opinion from another Oncologist in your area.
The way I understand it the surgery is now in the past and completed? That is always a good idea, unless the tumor has some complexity that renders it impossible to carry out surgery, or it has spread so much that it will worsen her general health so she cannot fight the other places it has spread to.
Feel free to share the details via my email address, if you want. I am not an oncologist, but I know the details of the clinical decision rules that oncologists must follow.
