My son has inherited the predisposition to sebacious cysts. His dad has them and his uncle as well.
He got his first one a few years ago at about the age 19. We went to a doctor and she said not to worry and if it got to bothering him she could remove it.
I leared from Dr Jonathan Wright that they can be treated with topical applications of Lugol's iodine. So we tried that and he did it for a couple of weeks to a cyst that had formed on his neck. It was about a centimeter across. He wasn’t very good at keeping up with the therapy. A month or two later we noticed that it was greatly reduced in size so he started working on it again. In a couple of weeks it was gone.
A year later he has a new one. This one, also on his neck is much larger and looks more the size like that his dad and uncle get, a couple of centimeters across. By this time we had learned about Miracle-Mineral-Supplement and he started to take it. The cyst started to react and it got very swollen and red and sensitive. At this point he started to apply Iodine topically also. He kept up with the Miracle-Mineral-Supplement but he was not very strict on his dosages. The whole process only took a couple of weeks of treatment and it is completely gone. He is very glad not to have a scar on his neck.
