Yes, I am pretty sure you can. I remember reading posts about it on the Miracle-Mineral-Supplement forum. You could use Miracle-Mineral-Supplement and CS as a search on there. I believe there is no contraindication, but most people separated the doses.
And you are probably familiar with Lugols, I can't decide which one for topical. But, the CS & Miracle-Mineral-Supplement for internal and Lugols externally, or ozonated Olive oil mixed with Lugols?
It seems like that kind of cancer should respond. I sure hope so!
