It is no different than the 1991 movie (I am dating myself, as well), "The Doctor." It was based on the book, "A Taste of My Own Medicine - When the Doctor is the Patient." Dr. Edward E. Rosenbaum was a rheumatologist diagnosed with throat cancer. When the movie based on his book, the physician "became" a surgeon! Even back in 1991, rheumatologists were unknown or not Hollywood-worthy. By the way, the book I referenced is a good read for physicians.
