Yes, in some women the breasts get worse before they get better. Just like the thyroid may swell temporarily as it gobbles up iodine. The whole architecture of the breast changes once the Iodine receptors heal and inflammation goes down.
Remember Iodine doesn't just nourish the breasts, it detoxes a poison--bromide. So there is a lot happening under your skin as the bromide leaves, kicking and screaming.
Adding a dab of natural progesterone cream to the breasts really increases the uptake of Iodine into the cells.
