Does the daughter have legal responsibility for medical decisions? Is she the healthcare POA (medical proxy?) Is the mother able to make her own decisions? Has she ever been declared incompetent by a court?
The question of "legality" might be complex.
And then there is the issue of "the right thing to do," which might not match the legal answer exactly.
Can you explain the background to this question a bit? What is your relationship to this mother/daughter pair? What do you think should happen?
Is the mother prepared to go for medical treatments? If this is the daughters own decision rather than the mothers it would be considered elder abuse and Adult protective Services should be consulted. if you are close to the family you could do this anonymously.
