All pretty normal - scans and checks are useful as they may pick up any problem long before you do (particularly if you are lucky and don't have very obvious unpleasant side effects). Occasional bone scans will check the state of your bone density which is important. Herceptin may sometimes cause some impact on the heart wall (it hasn't done anything to mine) so echocardiograms are normal too. One of the joys of this lark is that you go from someone who sees their local GP once a year (maybe) to someone with a surgeon, an oncologist, a cardiologist, a therapist and so on and so on.
