@KezzaG It's pretty common for the end of treatment to inspire depression and anxiety. My advice would be "get thee to a counsellor". I fell apart pretty much at this time and I've heard the same from many people. I saw a psychologist for a few months afterwards. While you're going through active treatment, it feels like you have a plan and are doing something positive towards recovery, then all of a sudden you're in freefall. I don't know your exact situation, but the general followup is reviews with the oncologist and surgeon on a regular basis. For me, having finished chemo and rads last September, I have been seeing my onc about every 3 months and surgeon every 6. At some stage my onc will cut me loose to 6 months and I will alternate between the two of them so that I see one every quarter. Are you going on to some sort of hormone therapy? I did ask my onc about recurrence and anxiety. His comment was that I needed to try to manage the anxiety and live as though I was cancer-free because to do otherwise, was not living. He didn't suggest that it would be easy. I'm doing my best but I do find the side effects from the hormone therapy do hinder this significantly. I'm also finding out that the hormone therapy may be more important for long-term survival than the chemo so I am determined to find a way to manage this. There's no easy answer - we all hope to be on the side of the stats that is good but obviously some will be on the other side. I think positivity can be over-rated - we can try for it but most of us fail. I'll settle for management. I don't have any evidence of cancer at the moment and until I find out otherwise, that's all that I'm working with.
As to info about ILC - you won't find a lot because there's not much there. The American lobby site seems to be the best source of knowledge (at least that I've found). But not surprising as it's a much larger population base. I do remember my onc saying not to read too much into the predictor calculators because they're based on ductal and the results won't be valid for ILC.
