Court forces 17 year old to take Chemo treatments against her will

I can see how that is relevant for someone who has a very low chance of survival, in which case they might want to go out peacefully without the chemo. But it isn't exactly relevant here, since the type of cancer is an easily treatable one (in comparison at least), in its earliest stages and with a very high chance of success.

The problem here is that the doctors have taken all of that into account and decided that chemo is the best option, but the girl has denied treatment despite this, not on grounds of QoL but because of misinformation given to her by her mother.

(Also the fact that the state has taken her under its care since it ruled the mother unfit to take care of her)

Ah no, I was writing half a mind about Flonne's post, my apologies for the ambiguity. I'm sure we can see why the mother and daughter are both incapable of coherent logical reasoning. In which case, the State has the power, and in this case is (lawfully) right, to take the daughter into protection (reads as custody too). The problem is that the daughter, being incapable of logical reasoning, will stop the treatment once she is legally adult, and unless the state or the medical team wants to spend even more money supporting the case that the daughter is an adult incapable of logical reasoning, this will be the most likely end result. A few months make little difference biologically, but in black and white it's a deal breaker. Prosecuting the mother will only make things worse, in that the daughter will take revenge on the state by going against the treatment. She's still a teenager, she's also having cancer, she's probably also having emotional problems because of her cancer and impending doom. It's all very complicated in psychology... probably.

And then she will probably die if she doesn't complete her treatment and eradicate the cancer, and the mum will accuse the doctors of killing her with poison. And if she lives, they will choose to believe that their prayers/alternative treatment/etc. worked but took a long time. Us as scientists... it's also our job to educate the lay people about science in general. Sadly, we cannot force people to understand. It's even harder for us to refute claims and such that are not falsifiable, as lame as they seem on first glance.

It's true though... chemotherapy IS using poison, in that the drugs have a much higher tox. profile. It's not necessarily about that though, since the dose makes the drug and the poison... too much of anything will kill you, be it water, sugar, salt, paracetamol, truth, lies...
