Breast care support nurses/ McGrath breast nurses - Do they follow through?

It’s interesting how varied people’s experiences are. I confess I have no idea how any allocation of breast care nurses works. However given limited numbers surely, as far as possible, breast care nurses should be allocated to those with greatest need? I certainly didn’t need a nurse at each appointment or consultation, whereas someone with a prior condition, or isolated or undersupported, would have found that assistance really helpful.
