Why would microwaves affect magnets?

I had this idea today. I wonder if it's completely ridiculous.

If I have a certain specific kind of cancer, would it be possible to find another person who is not related with the exact same kind of cancer, extract their cancer cells and immunize me with them? Perhaps it would stimulate the "not self" part of our immune system enough and sensitize the immune system to aberrant/different cell-surface proteins expressed in the cancer cell.
