The vet told us our 15yr old Bichon has Cushings and a soft tumor on the left side of his stomach. We give him straight 10ppm CS for his water and he just keeps hanging in there. It also helps his teethbecause they are pretty bad too. I have heard reports of people drinking large amounts of CS to boost the immune for fighting cancer and coming back a few months later with NO cancer. Cancer cells are said to dediferentiate in the presence of electro- Colloidal Silver . In other words they turn back to normal cells. It could'nt hurt to try it. But certainly do everything else you can to fight the cancer.
