I didn’t have a breast care nurse. But my oncologist’s nurse (and wife!), my senior oncology nurse and my surgeon’s nurse were all really helpful at one time or another. My senior oncology nurse recommended both my lymphoedema therapist (ten years on she’s still my go to person for my arm) and a counsellor when long term side effects had me a bit flustered. Both were excellent, not just professional but well suited to
my personality and preferences. Sometimes you just have to ask, but be prepared if they don’t know or can’t help. Best wishes.
