I went to my oncologist with my husband, before seeing my surgeon. My PCP set me up with his wife's oncologist to discuss my diagnosis. The oncologist's first question to me was whether I had already picked and met my surgeon - that startled me because it seemed so out of order. Let's find out what the diagnosis is and then proceed.
She went over the biopsy results and various scenarios regarding treatment options.
I asked about further scans and tests. She only wanted baseline blood work, tumor markers and vitamin D levels - no scans. She did a rather cursory exam and asked a lot of questions about medical and family history.
I told her that I wanted a BMX without reconstruction, if one was sick, the mate was also coming off and I would not want them replaced.
She recommended my general surgeon, telling me that he does the majority of BMXs in town and that I should call for an appointment as soon as possible since it had already been a month since my diagnosis.
The results of the BMX and Oncotype test would determine further treatment, and she did not need to see me again until after the BMX pathology and Oncotype results were back.
As soon as I got home, I called to make the appointment with the general surgeon, met him the following Wednesday and was in the OR a week later. Since my surgeon gave me the pathology results at my post-op appointment the following week, I did not see my oncologist again until almost 4 weeks later since my Oncotype testing was delayed because of insurance haggling.
I would suggest you have a list of questions written down and bring someone with you to the first appointment.

I actually saw my surgeon first as he had prescribed my annual mammogram. He set me up with oncologist after doing my lumpectomy. I keep getting rave reviews about my oncologist. I actually had my port put in right after seeing oncologist!

@Nurse4utoday Thanks

My breast surgeon set up my meeting with my oncologist. On my first appt she took down family history, personal history, also looked to see if I should have genetic testing, but since both of us decided since I don't have a family history of breast cancer it wasn't needed. Now genetic counseling is covered by my insurance now its something I want to look into.

My oncologist went over my diagnoses with me, explained all my options in regards to the different types of chemo I could take and there side effects. She also gave me a print out of the side effects as well. Then we discussed surgeries and radiation. After that I met with my nurse coordinator who gave me a rather large and yes overwhelming binder with a calendar in it. The binder gave me contact numbers to various personal that would be considered my cancer care team. Again all side effects related to the chemo combo where in the binder, along with ideas of how to ease these effects. There was also a list of foods for me to try to eat depending on my side effects. Also a list of reputable web sites to gain more information regarding cancer.The calendar is to keep your appointments straight as yes chemo brain (short term memory loss) is a real thing.
Wishing you the very best during and after these challenging times
