Is there a breast problem brewing or are her diagnostic tests a false alarm?

This will prove to be a false alarm, so you need not worry about opening a can of worms here. We know you understand fully the implications of gaining knowledge of this kind. We are not worried about you making a misstep, but we do understand there sometimes are difficulties in dealing with bad news, disappointments, and life difficulties that may be quite formidable in the perspective of most people facing that dilemma. So you need not worry about her in this regard in the near-term.
