In the early decades of the twentieth century, when the field of virology was not yet fully developed, this theory attracted widespread skepticism. Doctors pointed out that they did not catch cancer from their patients. Scientists such as Ludwik Gross, whose study of leukemia in mice played an important role in reviving the theory of viral carcinogenesis in the 1950s, were at first considered fringe figures for their conviction that a virus might transmit cancer from generation to generation. Gross, however, was deadly serious. Because mouse nursing studies from the 1930s suggested that a viral \u201cmilk factor\u201d could pass mammary tumors from mother to daughter, he considered raising his own infant daughter on formula in order to avoid the risk of intergenerational transfer of a possible human breast cancer virus. Following his findings and other advances in virology, by the 1960s the possibility that human cancer had viral causes seemed chillingly plausible.<\/p>\n<figure id=\"attachment_16593\" aria-describedby=\"caption-attachment-16593\" style=\"width: 398px\" class=\"wp-caption alignleft\"><a href=\"https:\/\/i0.wp.com\/circulatingnow.nlm.nih.gov\/wp-content\/uploads\/2019\/06\/sessoms-to-tannehill-7-11-1958.jpg?ssl=1\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" data-attachment-id=\"16593\" data-permalink=\"https:\/\/circulatingnow.nlm.nih.gov\/2019\/06\/20\/the-search-for-cancer-viruses-1966\/sessoms-to-tannehill-7-11-1958\/\" data-orig-file=\"https:\/\/i0.wp.com\/circulatingnow.nlm.nih.gov\/wp-content\/uploads\/2019\/06\/sessoms-to-tannehill-7-11-1958.jpg?fit=941%2C1200&ssl=1\" data-orig-size=\"941,1200\" data-comments-opened=\"1\" data-image-meta=\"{"aperture":"0","credit":"","camera":"","caption":"","created_timestamp":"0","copyright":"","focal_length":"0","iso":"0","shutter_speed":"0","title":"","orientation":"1"}\" data-image-title=\"Sessoms-7-11-1958\" data-image-description=\"\" data-image-caption=\"<p>Letter from Stuart M.

Both fundraisers and administrators at the National Cancer Institute realized that presenting cancer as a children\u2019s disease promoted far more urgency for cancer research than when it was framed as a disease which threatened adults. In particular, the opening of the film recalled a notorious cluster of potentially infectious leukemia reported among the children of the Chicago suburb of Niles, Illinois in 1961.<\/p>\n<p>Following Sandra to the Roswell Park Memorial Institute outside of Buffalo, New York, the film stepped back to explain the challenges that that faced scientists when they sought to demonstrate that viruses caused cancer.

For researchers at smaller laboratories, isolating and cultivating candidate human cancer viruses was among the most expensive barriers to joining the search. James Grace, the director of Roswell Park and an advisor to the Program, collected and cultured samples of possible cancer viruses for further study and distribution. Grace led viewers through one of the facilities supported by the National Cancer Institute, emphasizing their ability to mass produce viruses and ship them safely to laboratories around the country in specialized biohazard containers.<\/p>\n<div class=\"tiled-gallery type-rectangular tiled-gallery-unresized\" data-original-width=\"840\" data-carousel-extra='{"blog_id":1,"permalink":"https:\\\/\\\/circulatingnow.nlm.nih.gov\\\/2019\\\/06\\\/20\\\/the-search-for-cancer-viruses-1966\\\/","likes_blog_id":"52242398"}' itemscope itemtype=\"http:\/\/schema.org\/ImageGallery\" > <div class=\"gallery-row\" style=\"width: 840px;

Since \u201cthe human is a member of the animal kingdom,\u201d Grace thought it unlikely that they would prove the exception to the growing number of leukemia viruses identified in animals ranging from mice to monkeys. This rhetoric reflected the growing authority of experimental medicine and its faith that animal studies were accurate guides to human disease.<\/p>\n<p>The close of the film returned to Sandra\u2019s suburban neighborhood, leaving viewers with the hopeful message that \u201cMany scientists like Dr. Stewart and Dr. Grace believe that\u201d vaccination against cancer was a possibility, and with it the \u201clong-awaited cure for cancer.\u201d<\/p>\n<p>With the declaration of President Richard Nixon’s “War on Cancer” in the 1970s, the Special Virus Leukemia Program grew to encompass the development of vaccines against all kinds of cancers. It eventually spent more than the Human Genome Project on its search for human cancer viruses. Throughout, it was driven by the mission of not only understanding cancer\u2019s viral causes but using them to provide a cure for cancer. The conjoint images of threatened children and laboratory science presented by \u201cThe Search for Cancer Viruses\u201d film were an important part of the rhetorical push to advance this vast research program.<\/p>\n<p><em>Watch or download <\/em><a href=\"http:\/\/resource.nlm.nih.gov\/8600200A\">The Search for Cancer Viruses<\/a> <em> on NLM Digital Collections.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Circulating Now welcomes guest blogger Robin Wolfe Scheffler, the Leo Marx Career Development Assistant Professor in the Program in Science,<\/p>\n","protected":false},"author":19605840,"featured_media":16609,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_coblocks_attr":"","_coblocks_dimensions":"","_coblocks_responsive_height":"","_coblocks_accordion_ie_support":"","advanced_seo_description":"","jetpack_seo_html_title":"","jetpack_seo_noindex":false,"jetpack_post_was_ever_published":false,"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":false,"jetpack_social_options":{"image_generator_settings":{"template":"highway","enabled":false},"version":2}},"categories":[12763,1359464,51014],"tags":[24741,24742,490,4252,1096659,1569022,668,567032962],"class_list":["post-16588","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-collections","category-films-videos","category-guests","tag-1950s","tag-1960s","tag-animals","tag-cancer","tag-national-cancer-institute","tag-president-richard-nixon","tag-research","tag-united-states-public-health-service-usphs"],"jetpack_publicize_connections":[],"jetpack_featured_media_url":"https:\/\/i0.wp.com\/circulatingnow.nlm.nih.gov\/wp-content\/uploads\/2019\/06\/scientist_8600200a_feature.jpg?fit=900%2C400&ssl=1","jetpack_likes_enabled":true,"jetpack_sharing_enabled":true,"jetpack_shortlink":"https:\/\/wp.me\/p3xcDk-4jy","jetpack-related-posts":[],"amp_enabled":true,"_links":{"self":[{"href":"https:\/\/circulatingnow.nlm.nih.gov\/wp-json\/wp\/v2\/posts\/16588","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/circulatingnow.nlm.nih.gov\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/circulatingnow.nlm.nih.gov\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/circulatingnow.nlm.nih.gov\/wp-json\/wp\/v2\/users\/19605840"}],"replies":[{"embeddable":true,"href":"https:\/\/circulatingnow.nlm.nih.gov\/wp-json\/wp\/v2\/comments?post=16588"}],"version-history":[{"count":15,"href":"https:\/\/circulatingnow.nlm.nih.gov\/wp-json\/wp\/v2\/posts\/16588\/revisions"}],"predecessor-version":[{"id":25555,"href":"https:\/\/circulatingnow.nlm.nih.gov\/wp-json\/wp\/v2\/posts\/16588\/revisions\/25555"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/circulatingnow.nlm.nih.gov\/wp-json\/wp\/v2\/media\/16609"}],"wp:attachment":[{"href":"https:\/\/circulatingnow.nlm.nih.gov\/wp-json\/wp\/v2\/media?parent=16588"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/circulatingnow.nlm.nih.gov\/wp-json\/wp\/v2\/categories?post=16588"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/circulatingnow.nlm.nih.gov\/wp-json\/wp\/v2\/tags?post=16588"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}} |
