There are plenty of parasites (and other infections, for that matter) that
cause granulomas, but a granuloma is an accumulation of inflammatory immune
cells.  It is not a cancer, nor in any way related to cancer.

The "oma" at the end which may have mislead you (as in granuloma and
carcinoma) is simply (if I can hazrd a guess) a derivation from the Greek
meaning "body".

Cheers, Mark
