TF and ovarian cancer: This dose of FAC (non-transferrin-bound iron frequently elevated in blood from patients with iron-overload conditions [10]) was selected based on iron-overload conditions present in endometriotic cysts, which are reported to have mM levels of free iron [20–23] and in which endometriotic epithelial cells are considered the precursor lesions which may transition to ovarian cancer [20–23].
