2 studies

Study: Structural and morphologic characteristics of nodular goiter in chronic iodine deficiency status
The study shows that not having enough iodine leads to abnormal growths in the thyroid gland, which supports part of the claim. It doesn't look at other organs like the breast or prostate, though.
Study: Thyroid neoplasia associated with nutritional deficiency in cultured jade perch in Hong Kong
The study found that fish with too little iodine in their diet grew abnormal thyroid tissue, which supports the idea that iodine deficiency can cause unhealthy tissue growth in the thyroid.
