Hi Chantry, welcome! I am so sorry you are going through this right now, thank goodness all is well with the baby. What is her name? I am 36, living in Michigan. Like Juju said, there are lots of us "younger" women here, but age does not matter here on the internet, we're all here for each other 24/7.
Your surgeon does the surgery, not the chemo...so he will not be a good resource regarding the treatment plan other than surgery. And if you are not comfortable, or even if you are, consider a second opinion once you see the onc too.
More questions to ask/ items to ponder....
1. Did he get clear margins?
2. Is more surgery recommended? If so, what? If mastectomy is recommended, can he connect you with a plastic surgeon if you want reconstruction?
3. Consider getting copies of any and all reports (path, radiology, etc).
4. Consider taking a tape recorder and a friend/ husband. No matter how clear your mind is, it is nearly impossible to hear it all correctly
Lots of questions will be for the oncologist, who is the one that will have the longer relationship with you. I read what I could handle, and not too much information, so I could ask the right questions. Take it easy with reading though, it is easy to get scared unnecessarily.
You sound like you are doing really well! Glad you found us, and please do not hesitate to ask us anything at all...
