I agree that we need a moderator.
I hope the following doesn't open up a series of posts from people
claiming that every oddball parasite causes cancer, but I did some
searching and came up with the following potential parasite/cancer
associations. These are the only ones that I could find in the
Schistosoma haematobium (Trematoda: urinary bladder carcinomas in
humans). Pretty definate. Many references (i.e. Acta Tropica, 1979,
Spirocerca lupi (Nematoda: esophageal sarcomas in canids). Pretty
definate. Multiple papers, i.e. J. Parasitol. 1971, 58: 3-22.
Clonorchis sinensis (Trematoda: perhaps gall bladder/bile duct
carcinomas in humans). Possible. Many references, i.e. J. Path Bact.
1956, 72: 239-246.
Armillifer sp. (Pentastoma: perhaps Hodgkin's disease in humans).
Highly unlikely. Ann. Trop. Med. Parasitol. 1975 69: 503-512.
Taenia crassicolis (Cestoda: perhaps sarcomas in the rat intermediate
host). Possible. Numerous references, i.e. Nigerian J. Sci., 1972, 5,
Spiroptera neoplastica (Nematoda: perhaps malignant epitheliomata in
rats). Possible. Series of papers by Fibiger, J.A.G. Also see
Parasitol Today 1997, 15: 202.
If anyone knows of any more "scientific" reports of different parasite
species causing cancer (NO anecdotes please), then I would like to
receive the references.
