What to expect from first onc appt

I have my first obgyn oncologist appointment on Monday. I am in Canada. All I know so far is that invasive cancer was found during my leep. Something about 6 mm and 3 mm, I think. I was in such a state of shock when the ob called me. I don’t know which type of cancer. So she said she referred me to the obgyn oncologist and that’s who I’m meeting on Monday. MRI is scheduled for early January so I know they’ll need that info to tell us more. I don’t really know what to expect from this appointment and I am just dreading it so much. My husband is coming with me and I’ll bring something to write notes down.
