Please help me save my daughter’s life

After months of my daughter losing her vision, she was diagnosed last week with a tumor on the brain. The doctor is not sure that it is operable, so she was referred to a specialist who can not see her because they do not accept her insurance-United Healthcare/ Community Plan. I guess it is true healthcare is not available for the poor. It is non existent for us. Any and all suggestions, information or donations would be appreciated. Please help me save my daughter’s life.
