marlo thomas: my father founded saint jude children's research hospital because he believed no child should die in the dawn of life. in 1984, a patient named stacy arrived, and it began her family's touching story that is still going on today. vicki: childhood cancer, it's just hard. stacey passed on christmas day of 1986. there is no pain like losing a child, but saint jude gave us more years to love on her each day. marlo thomas: you can join the battle to save lives. for just $19 a month, you'll help us continue the lifesaving research and treatment these kids need now and in the future. jessica: i remember as a child, walking the halls of saint jude, and watching my sister fight for her life.
