I'm building/outlining a story in which a character has lung cancer and is hospitalized. This character isn't my MC, nor will he even been seen very much, but he, and his terminal cancer, are catalysts for the events of the story. I'm planning on it starting just on the day when he's hospitalized and I do intend for him to die, unfortunately. I'm wondering some basics:
Terms I might use that are repeated from his teenage brother's perspective. (the story is YA and mostly from this character's perspective)
Reasons that lead up to longer term hospitalization rather than just going in for chemo appoints regularly a la breaking bad. (story takes place over a couple of weeks)
Any sort of equipment that might commonly be around him or in use for him and, in general, how he might look, react, or be feeling physically. (hot/cold, numb/stabbing pains, etc.)
And any other info anyone might want to give.
It's a hard topic I want to get a lot of information on.
