Unfortunately, despite what this article says, there is a choice between fighting cancer or not: The best way to give up is stopping to eat (which probably isn't that hard if things like chemotherapy and severe illness pretty much remove any feelings of hunger).

Oh there are lots of ways to give up. I could refuse palliative chemotherapy, stop eating, overdose on opiates, drink a large glass of scotch together with my drugs, and so on. Yet when people say "you must fight" they don't generally mean, "take your meds and eat two full meals a day, and try to feel positive!"
