Fenben does work. I am using it right now along with my dog. Been on it 7 weeks. it takes awhile sometimes..up to 6 months to see any changes but yep..cancer is parasitic. OH and Ivermectin works as well but Fenben (Panacur) works better) SOME have also reported to use baking soda to cure themselves and that goes into the alkalinity of the body. HCQ has also been know to work for many things like Fenben.
