Immunotherapy or hogwash?

Awhile back, I wrote about a Phillipino patient who was eating pigeon meat based on the belief
that pigeons have the ability to make antibodies for MM. Supposedly, he knows a man who
still lives in the Phillipines and is doing well with this protocol while not getting modern
treatment for his MM. There was another thing I was told about shortly after Tim was
diagnosed that makes me wonder sometimes. I was told by a farm wife in Vermont, who
we have known many years, of a cancer patient she knows who was basically told by his doc that there
was nothing more they could do for him. I am trying to remember what type of cancer he
had. I think it was a lymphoma and I also think he had other issues on top of that. I can't remember exactly. Anyway,
the guy started doing his own thing and what he supposedly did was inject a cow with his cancer
cells. Then he makes yogurt from the milk of this cow and eats it. He swears that the cow is making antibodies to his disease and this is what is keeping him alive long after the doctors
"wrote him off." This farm wife owns the dairy farm across the street from a house Tim's
folks bought 30+ years ago. She told me, "anytime you want to try this, we'll supply the cow."
It sounds crazy, I know, but I have to admit that it makes ya think. It is true that different
species are prone to or kinda exempt from different illnesses. We know that animals have
immunities to things we don't and vice versa. If a breastfeeding mother can
pass on immunities to her child through breast milk, does this process sound so very ridiculous?
I don't know. I've heard crazier sounding things than this. It sounds like one of those
"couldn't hoit" situations, unless you're the cow.
