I'm already a licensed nurse and a medical student so I can relate to this one perfectly. Heck, my own grandfather is hospitalized right now with two primary cancers. Seeing oncology related cases is also part of the daily grind when dealing with charity clinical consults. I live in the third world country and people here don't have money to spare for medical expenses.
I could say that another aspect you may need to emphasize is how medical expenses also affect the quality of life for patients. Those selected about their care due to the limit of what their insurance carriers could provide for them. This post has a lot of humanity in it and I'm glad it got upvoted by curie.
