Oncologist appointment tomorrow - what questions should I ask?

After being diagnosed on 18th January and going through all the various test, I finally get to see the oncologist tomorrow. Would like to hear from anyone who has any suggestions about what questions would be good to ask. 

Also what are your experiences of how long it took for treatment to start after first oncology appointment. As my breast cancer is grade 3 and fast growing, I'm worried about it spreading, before my treatment even gets started. 

Was it suggested you have a PICC line or port?
