This is a tough one. Stage 4, from my understanding means that it has sperad or matastisized as they say.
As a Canadian, cost isn't an issue. We have medicare, and I will bitch about it, but it is free and there when we need it.
But if I'm being honest, even now at 50, and trust me, I have no plans to leave this planet anytime soon, I'm going quality over quantity.
I'd fight in my own way, holistic treatments, diet, whatever might give me a decent quality of life for as long as I could have it. But I don't want to be sick and miserable. I don't want to put my family through that. I don't want to put me through that.
I would choose to live out my years or months without being a martyr or an dexperiment, as you said. I would choose to spend my time making memories and having fun with theose that I love. But that's the thing, isn't it? THAT'S the debate, I can choose, it costs me nothing in terms of money either way.
I think she's made her choice. I defend her right to do so, but, realistically.....yeah...you know.
