The most common medical procedure for getting rid of skin cancer is the squirting of liquid nitrogen on the cancer sore which freezes it off. It causes a bit of pain for a couple of minutes but not long, and then the sore scabs up and drops off and doesn't leave a mark. I've been having this done over several years and the last time went in after a year and a half without treatment and there was only one found on my scalp.
Also after starting to drink my own urine these little cancer sores began disappearing on their own which is what my MD from India says that is often used in her home country. I still need a nitrogen burn off from time to time but it has been about a year since the last one and I don't currently see any of them on my body.
Drink pee. It's free, and it cures a host of ills.
