"Hypothesis: Iodine, selenium and the development of breast cancer"
"
Recent work with animal systems seems to support an antitumor e€ect for iodine. In dimethylbenz[a]anthracene-induced mammary carcinoma in rats, iodine supplementation has been shown to have a suppressive e€ect on the development of this disease [32]. This suppressive activity was enhanced when iodine treatment was combined with progesterone (medroxy-progesterone acetate) [33]. The suppressed tumors were found to have a signi®cantly higher mean iodine content than nonsuppressed tumors, with uptake apparently enhanced by progesterone [33]. The enhancement of iodine uptake by progesterone has been observed in other hormone-dependent tissues including the uterus and oviduct [34]. We are presently initiating an analogous study in patients with metastatic breast cancer, in which subjects will take iodine supplements in combination with conventional progestin treatment [9]."
