I definitely understand wanting to just have it out (I'm waiting on my surgery date and every day it's a mixture of dreading the surgery and yelling 'get out get out get out' like a long overdue pregnancy).
I want to pipe in that if you don't understand something your oncologist or surgeon are telling you; Ask them. Tell them it's confusing. They know you're under a lot of pressure and stress, and probably even have information print-outs on stand by. There are no stupid questions. <3
I was initially lined up for a chemo first approach to treatment as part of a research study that aimed to observe the effects on tumor shrinkage which would also test the area (because I have a lot of surrounding calcification) for responsiveness to the treatment. It may have been something like that?
It's probably worth calling your surgeon to talk about it again, I hope you get your answers.
