> Some things with interesting iodine research: skin cancer, breast cancer, type 2 diabetes, asthma, polycystic ovaries, fibrocystic breast disease, other cancers. But yeah, it cures goiter...

When I search for breast cancer and iodine, I find links that suggest iodine may help prevent that disease - and Japan’s low rate of the condition is potentially related to high consumption of iodine.

Are you saying that all those conditions are due to excess iodine?
