What to expect at 1st oncology appointment?

Hi all. I am anxiously awaiting my first oncology appointment next week and I am so nervous about it. It will be 3 weeks since my pathology report came back positive for CC and my mind is just racing. My gynecologist set up the appointment so I have not spoken to anyone at oncology to have an idea of what will happen. Can anyone provide some clues? I am in the US, not sure if this makes a difference.
