Carcinogenic parasites are parasitic organisms that depend on other organisms (called hosts) for their survival, and cause cancer in such hosts.Three species of flukes are medically-proven carcinogenic parasites, namely the urinary blood fluke (Schistosoma haematobium), the Southeast Asian liver fluke (Opisthorchis viverrini) and the Chinese liver fluke (Clonorchis sinensis).
A transmissible cancer is a cancer cell or cluster of cancer cells that can be transferred between individuals without the involvement of an infectious agent such as an oncovirus. [ 1 ] [ 2 ] The evolution of transmissible cancer has occurred naturally in other animal species, but human cancer transmission is rare. [ 2 ]
This is the only member of this group of viruses known to cause human cancer but other polyomaviruses are suspects for being additional cancer viruses. [citation needed] HIV does not directly cause cancer, but it is associated with a number of malignancies, especially Kaposi's sarcoma, non-Hodgkin's lymphoma, anal cancer and cervical cancer.
It is not otherwise spread between people. [3] The parasite is only known to reproduce sexually in the cat family. [9] However, it can infect most types of warm-blooded animals, including humans. [9] Diagnosis is typically by testing blood for antibodies or by testing the amniotic fluid in a pregnant patient for the parasite's DNA. [4]
It is found in Africa and the Middle East. It is the major agent of schistosomiasis, the most prevalent parasitic infection in humans. [1] It is the only blood fluke that infects the urinary tract, causing urinary schistosomiasis, and is a leading cause of bladder cancer (only next to tobacco smoking). [2] [3] The diseases are caused by the eggs.
