Evidently “the cancer cell’s pursuit of an individual career may not be as quixotic a pursuit as once thought”:
Scientists studying Sticker’s Sarcoma, a cancer of dogs, recently discovered two rather surprising facts about the disease: (1) a transmittable agent causes the cancer, (2) the cells in the tumors caused by Sticker’s are definitely dog cells, (3) the cells in the tumors bear no genetic relation to each individual animal with the disease but (4) all the tumor cells in every case of Sticker’s have the same exact genes.The only possible conclusion: Stickers Sarcoma is not a true cancer but rather a communicable pathogen that originated from one mutated cell in one dog that somehow managed to escape its original body and infect new hosts!
