Help! I can't remember...

I remember there was a movie about a bunch of med students. Near the end of the movie, the doctor (professor) informed them that they were to be the patients and have some of their medical tests, etc. done on them. I saw someone mention the name of the movie on here a little while ago, but can't find the post now. What was the name of that movie? Thanks!

I believe it was "The Doctor", based on a book written by an actual doctor who had undergone treatment for cancer. I remember the scene in which he tells the students what they will be subjected to after being admitted. Including every single one of them having a Foley catheter inserted!
