Anyone help please?

Hi Ladies I have been reading your posts and wondered if anyone could give me any advice regarding my first meeting with the Oncologist (I go Monday) I got diagnosed 3 weeks ago, had lumpectomy, and was told that I had Stage 2, with 2.5 lymph node involvement and had to have chemo, rads and tamoxifen. I am really struggling with the terminology of it all, and did not ask any other questions other than really what they told me. I would like to know if there are any questions I should ask when I meet them on Monday so would really appreciate any help you could give. They havent really told me what will happen at the meeting, other than I will be informed of my treatment plan, I havent had any scans etc, are they arranged if needed by oncologist? Any advice would be much appreciated.
Thank You
