i used tincture of iodine painted on my breast that had a benign lump. prior to the doctor said she could aspirate it but the lump may or may not return. i did my own research. within two week of application of the iodine the lump was gone. I did have a return lump 2 years after that which i again used iodine and again the lump went away never to return.

The book Iodine Crisis is a very good read.
