I have never used DMSO on a breast lump, I have used it for other reasons and I found it to get some what stingy or itchy in areas where I used it until someone on Earth Clinic suggested mixing in or using it with castor oil. Castor oil took the sting out of the application of DMSO.
That being said, I have had quite some experience with breast lumps. I have had lumps removed between 19 and 24 years of age. When older, I have applied iodine for my cystic breast lump removal. However, there was a time I had to call on the Lord for help on what to do. The interesting thought here is, I didn't say I need you to heal me now, which is a good prayer too, instead I said, "Lord I need you to do something for me now because the doctors are scheduling a second test! While on my knees in prayer the Lord showed me a plate filled with nothing but green vegetables, and that was what I ate for about a week until my appointment. When they gave me the confirming x-ray or scan there was No lump. The doctor began to tell me how sometimes the machines malfunction, but I knew the Lord had given me a quick detox and dissolved and flushed out the poisonous lump.
With just some simple obedience from me to do a good old fashion vegetable fast, I was lump free. A fast often from our usual eating habits May be all we need to heal. I thank God for sharing this wisdom for healing with me.
