I have been taking 2 Iodoral per day for about a month and within the last week have been noticing sensations a few times a day in my right breast and above the breast toward the armpit. For years I have had fibrocystic breasts. No growths that needed to be explored further ever showed up in the mammograms and sonograms. I am wondering, though if there could have been microscopic changes in that breast toward a cancerous or precancerous condition that the Iodine is somehow working on. I assume that is what is going on and so am not concerned/alarmed about the sensations [which are mild and exactly where I would expect them to be based my fibrocystic history.] Has anyone had similar experience with breast sensations while on Iodoral? Does anyone out there with more Iodine supplementation than I have feel this is cause for alarm?
