I asked his Dr. about this and they were very hesitant to give the ok. Apparently when your WBC and platelet count is down the enema can do more damage and further deplete the platelet count? Sound right? Who knows. In any case, we bought him the kit to do his own and he's only had to use it a couple of times. I started him using flax seed in his oatmeal every morning and that has really helped him out. We believe the size of the tumor on his pancreas has shrunk and perhaps that is helping as well. All I know is that he feels a little better and that's what counts most.
