Are those "other options" going to be "sitting here and dying naturally, maybe drowning in your own vomit, maybe dying of starvation"?
I have a hard time believe things are going down like, "You have cancer. We can treat it and you'd be fine, but you know what you should do instead? Kill yourself"
On the other hand, I do believe (and want) doctors to be like, "You have cancer. We can treat it and you might get a few more months with very poor quality of life. You may wish to consider these other options"
