Dietary isoflavone intake among breast cancer survivors and cancer-free women.

ABSTRACT:

Background/objectives

Isoflavones are estrogen-like compounds found in plants and their health effects remain equivocal. We investigated dietary isoflavone intake and its associated factors in Korean breast cancer survivors, with a comparison to cancer-free women.
