There is no doubt that SV40 is a human carcinogen, SV40 is definitely something you don't want in your body. The virus works in tandem with asbestos or by itself to transform healthy mesothelial cells into cancerous ones.
The United States, Great Britain, France, Belgium, Italy, and New Zealand all have confirmed that with respect to the presence of SV40 in human mesothelioma. Their results point to a solution to an enigma that long puzzled researchers. At least 20 percent of mesothelioma victims report no asbestos exposure, and only 10 percent of people who have had heavy exposure to asbestos ever develop mesothelioma. The experiments suggest that SV40 may be another factor at work in the tumors. Two very recent studies, from Finland and Turkey, found no SV40 in domestic mesothelioma samples but did find it, respectively, in American and Italian samples. The authors observe that their negative findings lend support to the theory that contaminated polio vaccine is associated with the disease: neither Turkey nor Finland used SV40-contaminated vaccines. Today Finland has one of the lowest rates of mesothelioma in the Western world. The virus has also been located in other kinds of tumors. More than a dozen laboratories have found SV40 in various kinds of rare brain and bone tumors. In 1996 Carbone reported that he had found SV40 in a third of the osteosarcomas (bone cancers of a type that afflicts about 900 Americans a year) and nearly half of the other bone tumors he tested -- research that has since been confirmed by numerous laboratories. The virus has also been detected in pituitary and thyroid tumors.
The possibility of a link between SV40 and brain tumors is particularly intriguing. Like mesothelioma, brain tumors have become dramatically more common in recent years. Brain tumors will be diagnosed in about 3,000 children in the United States alone this year. In 1995 Janet Butel, the chairman of the department of molecular ...
