If people are terminally ill, with almost zero chance for survival, and they agree to any theoretical treatment, there should be no repercussions. If nothing else, like in this case, it establishes this one technique does not work.
But in this case it did even more. It actually makes sense that an infection *might* result in the immune system “seeing through” a tumor’s defenses, and thus realizing it should be attacked.
Tumors go to elaborate lengths to conceal themselves, and just recently it was discovered that they use a large amount of a particular protein (?) to do so. Block that protein, and the tumor might be exposed, or so goes the theory.
So in truth, it is not just a technique that has been disproven, but an entire concept, so similar techniques are also less likely to work.
Fecal material certainly didn’t kill my cancer.
