Dear Collette
That's a pretty rational feeling - you've got through the surgery but now feel really concerned about what's next. You're not being an ostrich, just honest. Everyone who has been diagnosed with cancer probably has had at least one, if not a lot more, profound wish that it would all go away. And there is an outside chance that's what will happen. No problem with nodes, no problem with margins! But your medical team wants to try and give you the best chance of never having to face this again. So if they have any doubts, or if there are still some lingering problems, they are going to suggest further treatment.
That will vary. So will your physical and emotional reactions to those treatments. It's worth remembering that your experience may be entirely different from that of others having apparently the same treatment. Cancer isn't one thing - and treatments vary too, especially in how people react. Make a list of things you want to ask at your appointment, or take a trusted friend or relative with you to do this. Just as with the BCNA, there are no silly questions. Anything you don't know and/or want to know is worth an answer. If your follow up is with your surgeon, ask about a referral to an oncologist, whch is the next step if there is further treatment. It helps to be active in your treatment - your medical team know about how to treat your body, but you know about treating your mind. A good counsellor, even for a short time, can be really helpful in settling your anxiety and planning ahead. Your GP can assist with a referral.
Best wishes for your next appointment.
