Help William with medical bills

Hi my name Sylvia(Toby). I'm try to help my son William with his medical bills he has brain cancer. They cannot do surgery because of where it is. They are trying to keep up the bills. They have no insurance so it's all out of pocket. He is at the point where he can't work. He has a daughter (Elvia) that's in high school. She does a good job of helping her daddy.
