Local teen Hannah Disbro and her family are remaining upbeat and asking for prayers after they were informed last week nothing more can be done medically to cure Hannah’s cancer.In addition to prayers, Hannah, 18, has turned to an all-natural diet of fruits and vegetables in hopes of curing her disease.“We’re staying positive and we’re doing all we can,” said Hannah’s mother, Pam Davis. “We were told last week at Vanderbilt she would no longer be a candidate for chemotherapy as far as a curative treatment. She will continue to receive care at Vanderbilt, but their focus will be more on comfort.
