That's basically how they treated my melanoma which was diagnosed more than
ten years ago on my face and scalp. They would squirt them with liquid
nitrogen (which is -320 degrees) and they would develop a small sore and fall
off - in about a week.
I would have to go in and have this done every six months as they would pop
out on my scalp - which is primarily bald, that often. This was as a
result of over exposure to sunshine primarily in Southern California where I
lived for a couple of years.
About eight or ten years ago for other reasons I began to practice urine
therapy, as in drinking my own pee - on a daily basis. My scalp began to
slowly clear up and I went from six months to a year between nitrogen visits and
it's now been three years since I've had any melanoma on my face or scalp.
This was a totally unexpected "side effect" to my urine therapy which
I continue on a daily basis to this day. Initially my dermatologist was an
East Indian doctor and I told her of my urine therapy practice and she told me
to keep it up. She said that many people in her home country practiced it
with good benefits there too.
