The following study shows the benefits of iodine to fibrocystic breast disease. This study appears to indicate that iodine deficiency is involved in the etiology of fibrocystic breast disease. University affiliated breast-treatment clinics. The numbers in study 2 increased over the review period so that 1365 volunteers were being treated with molecular iodine by 1989. The fibrocystic breast reacts differently to sodium iodide, protein-bound iodide and molecular iodine.
Molecular iodine is nonthyrotropic and was the most beneficial.
It has been reported that dietary restriction and chemical blockade of iodine causes histopathologic changes in peripubertal female rat breasts. It is the older rat that experiments will more closely parallel the human condition.
