My Sisters Keeper (2009)

Sara (Cameron Diaz) and Brian Fitzgerald (Jason Patric) have just been informed that their young daughter Kate (Sofia Vassilieva) has leukemia, and that she only has a few years to live. The doctor suggests to the parents that they try an unorthodox medical procedure of producing another child in a test-tube that would be a perfect match as a donor for Kate. Sara will try anything to save Kate, and they have anew baby Anna (Abigail Breslin) to be used as a donor for Kate. The first thing they use is blood from the umbilical cord for Kate. As years go on, the doctors must take bone marrow from Anna to give to Kate. At age 11, the next thing Anna must give to her sister is a kidney. Anna has had enough of all of these medical procedures, and she decides to sue her parents for medical emancipation and the right to decide how her body will be used.
