Smaller breasts?

I have just recalled something that occurred over a year ago when I first began to take iodine. My breasts got "smaller". Not a very noticeable change but i feel as if they were slightly swollen before (not painful, just a bit uncomfortably big) and the Iodine fixed that. I'm just curious as to why this is, if anybody has an opinion on the matter?
I know that Iodine is crucial to breast health and Breast Cancer prevention. Tweet
