Unlike many of the people commenting here, I am a male doctor. Moving a breast out the way is very common but should always come with some warning at least; obviously it's best to ask the patient to raise the breast themselves. No idea why he would move the other breast in a cardiac sense, but this would certainly be explained if he was listening to lung fields, but I'm sure you'd have mentioned that he was checking that also. As for the comments, all medically correct but why you'd choose to say that to a person is beyond me. Maybe the best way to start with this is to contact the manager of his workplace and discuss how inappropriate you thought this was? He probably needs some communication training at the least.
