Hi,
My husband had good experience with cesium. I am going to update his progress for alternatives, and he has tried several.
He is not taking it now, but wants to buy some more and start again.
In a nutshell, he has changed his diet, along with cesium, B17, and LDN, and his tumor has not grown at all in 4 months.
He did go through a couple of months of denial, and did not maintain his vegetarian diet and ate junk food, but all in all, he is holding steady.
