@sbryant Yes, this is a frightening. Although the oncologist will have a copy of your pathology report you could take your copy with you to the oncologist and ask for an explanation.

I think it's a good thing not to do much research on your own and especially stay away from Google searches. These are unlikely to take you to valid and reliable sites if you want to read anything helpful.

Who do you share your worries with? Do you have a family or a spouse who can support you through this difficult time period?
