 In rare cases, such as some advanced cancers, treatment decisions for a pregnant woman necessitate a choice between saving her life and that of the fetus, or other dramatic trade-offs. In such cases, there is general consensus (especially in the wake of the Angela Carder case discussed above) that the primary consideration should be saving the life of the mother (i.e. see Puls, Terry, and Hunter 1997). Charles Weijer (1998) points out, however, that in some cases a pregnant woman's decision to refuse treatment and sacrifice herself for her child should be counted as an autonomous decision worth respecting, and that we should not assume that only self-interested decisions can be autonomous.
