I was going to suggest email also. I use email with my husbands oncologist just because it's often easier. If I think there's something she should know or I have questions, I take care of it. Trying to get through her office staff is a challenge unto itself and this way we both get to address it when we have a free minute instead of in the middle of someone else's care. It works really well for both of us. She doesn't hesitate to call me or ask me to call her if she feels we need to talk about something in more detail.
