betty rollin reports. >> for years, natalie albin endured aggressive treatment for leukemia. she wound up in memorial sloan kettering hospital in new york. death was near. >> she'd had years of chemo. she was done with it. there was nothing left for her body to tolerate. >> her daughter, fran cronin, says that what the family wanted at this point was a quiet time to be together and say good-bye. >> but the doctors kept on coming back to us and asking us if we'd like to do tests, what else we could do, and we'd have to say, well, what kind of difference will this make? is this going to change the prognosis? no. this might extend her life for a couple of months. what quality of life is she going to have? nothing really better, can't guarantee. in our effort to say good-bye to my mother we were always being interrupted by the hospital's own need to be service-driven. they weren't about hospice care. it wasn't about saying good-bye. their role and their interaction with us was to provide treatment. >> we are wired as human beings, thankfully, to when in doubt you fight for life n
