herrena, must have been quite a day. Hope you're okay amidst it all. It's so v.hard for you too. Were your DC okay without you?? Hope they were.
fwiw, if your mum wants them to, the Oncologists will be more specific in terms of odds. They have a computerised programme which they input your pathology into and it comes out with stats. So they'll tell you for example that if you go through all the treatment you've got an 80% chance of no recurrence. That's what I was told when I asked.
Having said that, I'm the sort who needs to know everything. Clearly I don't know your mum, but you do, so all you can do is know as much as you can and weigh up what's best. This is hugely anecdotal, but I remember so clearly the point at which all the scans were done, so all the pathology in and I finally had all the answers they could give me. To know that a) it hadn't spread beyond nodes, so b) was deemed highly treatable and therefore curable too, and that c) I had an 80% of no recurrence made me cheer. Literally! I felt from that point on that I could do Breast Cancer, because I knew what I was facing.
Being a bit rambly now, but I think most of us on here would agree, the hardest part of all of this is the unknown. That never leaves you once you're diagnosed and obviously your mum still has scans to go, but when they're done and results are in, maybe your mum would be better off asking the Onc for stats. Am saying that from a pov of optimism. As yes it's cancer and yes that's totally shit in every way, but if the MRI shows it's not in her nodes, then her odds are still pretty good - better than mine certainly. My odds at 80% weren't bad and it was in my nodes. So say scans give great news, so it's contained in the breast, then (guesstimate) she's got a 90% chance of no-recurrence or even higher, well I'd say she might get a huge boost from knowing that. That it might actively help her through treatment.
Sorry to go on and honestly do feel free to ignore me. Just something in what you said, brought it all back. Bloody cancer. Such a sod..
