Can I refuse allowing an resident intern to examine child?

When we go to my daughters oncologist they subject her to 4 examines in one visit! 1 with the nurse checking her vitals 2 with intern resident doctors and then finally with her oncologist. Each time she freaks out and screams and cries. She is only 2 almost 3. I find it irritating that they are using a toddler to learn on especially since she doesn't like it to begin with. My daughter has had doctors probing and poking her for almost 3 years now. She doesn't like it and it upsets her. Can I just tell them no I do not want them to use my daughter for them to study on? I know they need to learn some how but why use a child that is obviously extremely upset by the multiple examinations?
