许多癌症可能由寄生虫引起 Many cancers may be caused by parasites

许多癌症可能由寄生虫引起，或者它们实际上是癌细胞。一些采取杀寄生虫疗法的癌症患者能够摆脱他们的癌症，这意味着他们的癌症确实最终与寄生虫有关。

国际寄生虫学杂志，第24卷，第6期，1994年9月，第833-843页发表的一项研究表明，肝吸虫感染Opisthorchis viverrini可引起胆管癌，这是胆管上皮的癌症，这是最严重的结果。肝吸虫感染。

该研究报告称，肝吸虫感染是泰国东北部的一个主要公共卫生问题，大约30％的居民患有侥幸。该地区的大多数居民都是老挝后裔，他们喜欢吃生鱼，这些都可以吸食侥幸。

该研究回顾表明肝吸虫感染与胆管癌之间存在密切关系。该寄生虫在该地区持久存在，尽管常用吡喹酮，并通过政府资助的计划广泛传播健康教育信息。

来自该地区癌症登记处的数据显示癌症在感染肝吸虫的个体中非常常见。

另一篇发表于Mutation Research / Fundamental and Molecular Mechanisms of Mutagenesis，第305卷，第2期，1994年3月1日，第273-281页的报告显示，日本血吸虫（Trematoda）感染可导致人和动物的癌症。

早期报道已经发现，血吸虫血吸虫感染可引起膀胱癌，而日本血吸虫则与肝癌或肝细胞癌和结直肠癌有关。

中国和日本的研究人员进行了流行病学分析，发现日本血吸虫感染是肝癌的危险因素，就像肝炎病毒感染和饮酒一样。

Many cancers may be caused by parasites or they are actually the cancer cells. Some cancer patients who take parasite-killing remedies are able to get rid of their cancer, which means that their cancers are indeed at last parasite-related.

A study published in International Journal for Parasitology, Volume 24, Issue 6, September 1994, Pages 833-843 shows that liver fluke infection with Opisthorchis viverrini can cause cholangiocarcinoma which is the cancer of the bile duct epithelium, which is the most severe outcome of liver fluke infection.

The study report says that the infection with the liver fluke is a major public health problem in Northeast Thailand, where approximately 30% of the residents live with the fluke. Most residents in this region are Laos-descendants who enjoy eating raw fish, which can harbor the fluke.

The study review demonstrates a close relationship between the liver fluke infection and the bile duct cancer. The parasite is persistent in the region although praziquantel is commonly used and health education information is disseminated widely through government-sponsored programs.

And data from a cancer registry in the region shows that cancer is very common in individuals who were infected with the liver fluke.

Still another report published in Mutation Research/Fundamental and Molecular Mechanisms of Mutagenesis, Volume 305, Issue 2, 1 March 1994, Pages 273-281shows that infection with Schistosoma japonicum (Trematoda) can cause cancer in man and animals.

Early reports have already revealed that Schistosoma haematobium infection can cause bladder cancer while Schistosoma japonicum has been linked to liver cancer or hepatocellular carcinoma and colorectal cancer.

Researchers in China and Japan conducted epidemiological analyses and found that S. japonicum infection is a risk factor for liver cancer just as hepatitis virus infection and alcohol consumption.
