Data clearly show that hormone replacement therapy reduces the risk of
cardiovascular disease and osteoporosis in postmenopausal women. Howe
ver, questions still exist about the risk-benefit ratio in women with
a history of estrogen-dependent tumors. The authors argue that objecti
ve evidence now indicates that the protective effects of estrogen may
well exceed the theoretical and unproven cancer risks, and they argue
that until data from prospective, randomized trials are available, rec
ommendations regarding hormone replacement therapy in cancer survivors
must be individualized.
