I have talked to cancer patients and treatment really violates people. You go through endless tests, get treatments with horrific side effects and basically are just treated like an object. I have heard several times that they wanted to stop treatment just because it was such a terrible experience physically and psychologically. Not sure how to do better but it’s understandable.
Even in countries that have functional medical systems, medical treatment can be very de-humanizing. It's not something that may every go away, as medical practice fundamentally clashes with most people's idea of selfhood.
