17 year old wants to refuse chemo

I have a friend from when we had children together in the NICU. This child spent 8 months in the NICU, and then was in and out of the hospital many (many) times. She wasn’t expected to live to 2, then at age 7 or 8 she had a serious problem, stopped breathing many times and really had a loss of cognitive function too. Over the years, more issues. Finally at age 16, the daughter said ‘no more’ and even though she wasn’t really capable (legally) of making that decision, after many conversations with doctors and hospice and family, they honored her request. She died 1 month before her 18 birthday, having left school and just spent her time dancing and being with friends for 18 months or so. I fully supported this decision. If she was still alive, she’d be in pain She was never going to ‘recover.’

I do not think this girl or her mother have put nearly the time or research into their decision as my friend’s daughter did. They claim to be ‘fighting’ the cancer, but they are not fighting anything. They don’t have a religious objection, don’t have an alternative plan.

I’m not worried about civil rights. I think all children should be vaccinated, even if parents object, because it’s for the good of society.
