I have one to deal with too and Miracle-Mineral-Supplement is not quite getting to it and so far nothing is, including Antibiotics used long before Miracle-Mineral-Supplement . Miracle-Mineral-Supplement , MMS/DMSO, Antibiotics , high dose vitamin C, iodine/DMSO patches, magnesium chloride/DMSO patches and whiskey patches all control its inflammation quite well, but none would get the frigging thing out for good. I suspect that old cysts in the gums are so well patched up by scar that not much wants to get through short of a knife. It looks like the only option in my and possibly your case is a surgery, be it self inflicted or professional.
When it comes to your kidney "cyst / tumor" congratulations on that and thanks for the info.
