Iodoral & Nasal Polyps

Hi, I've been taking 37.5mg of Iodoral along with magnesium, selenium, vitamin C, opti-Zinc, NAC, vitamin E and B complex for over three years.  About 10 months ago I developed a nasal polyp only on the right side of my nose.  ENT wants me to have surgery to remove, but the chances of polyp regrowth are high.  He believes it is benign, but would need to have surgery and biopsy to be certain.  I'm more worried about surgery since its general anesthesia.  Has anyone else experienced nasal polyp growth while on Iodoral?  Any suggestions for shrinking it?  Should I increase Iodoral?  I've successfully shrunk my thyroid nodules using 37.5mg of Iodoral.  I've was feeling great until the nasal polyp.  Bummed and don't want surgery.
