I agree with all of your reasoning (except that you seem to be talking about the 2nd compton scatter of the gamma). I just wanted to give you a 'heads-up'. I am not the expert here. - It would be important to know what types of volumes are involved and how you defined the geometry in question. This is probably more an issue for the geometry category. The navigator's step does not stop at the boundary because the geometry returns a distance that is larger than the real "distance-to-out" for the volume 'physiBreast'. But before we can jump to this conclusion you must ascertain that you do NOT have any overlapping volumes in your geometry definitions.
