iodine, selenium and boron. i would go with high amounts on each - 100-300mg lugols, 400mcg(maybe up to 800mcg at first) of selenomethionine and 15mg of triboron.
as for cancer, webster kehr is my go-to guy. you can trust cancertutor.com to give you a good education into whats available and what will work for you. i like the food protocols and electromedicine. read carefully and for a long time. look for stuff that pertains to you. the site is well laid out. you cant hardly waste time reading anything there.
