Love Canal, USA

Residents of Love Canal, in the Niagara Falls region of Western New York, were alerted to signs of a toxic waste crisis involving the lethal chemical byproduct dioxin in the late 1970s. Residents learned about the crisis through news media, community activism and research, and their own visceral experiences – they could smell noxious fumes, noticed black sludge seeping into their basements, and saw children falling ill. Activists and academics carried out community-based research to survey the area in an effort to understand the extent of the hazard and its effects – data that they saw as missing, at the time – in turn generating evidence of changes in health and pregnancy abnormalities. In doing so, members of the community aimed to hold corporate and government stakeholders accountable to evacuate residents, organize remediation, and strengthen scientific studies and interventions to care for residents. Regional health authorities, however, dismissed community-based studies as “useless housewife data”. Activists responded by scrutinizing government and scientific studies, critiquing a lack of ecological validity and trustworthiness. Residents and community groups’ advocacy contributed to their exercise of epistemic authority, the creation of archival records and initiatives tracking the crisis over the last five decades, and wider public attention to Love Canal and other sites like it.

This study is published in the Japanese Journal of Clinical Oncology. This journal is for clinical oncologists and publishes articles about medical oncology, clinical trials, radiology, surgery, basic research, epidemiology, and palliative care. It was established in 1971 as the first journal from Japan to publish clinical research on cancer in English. It is a sister-journal to the Journal of the National Cancer Institute. It is also linked through the Oxford Journals.

The object of this study is to observe whether or not there was an overdiagnosis of thyroid cancer after the Fukushima nuclear disaster in 2011. They did this by comparing the observed prevalance of thyroid cancer in the Thyroid Screening Programme with the estimated historical controls on the assumption that there was neither nuclear accident nor screening intervention.

They calculated the observed/expected (O/E) ratio of thyroid cancer prevalence for residents in Fukushima Prefecture that were below the age of 20. Observed prevalence was calculated by the number of thyroid cancer cases detected by the end of April 2015. The number of detected cases was corrected for screening rate by multiplying the inverse of the age-specific screening rate. The expected prevalence was obtained from another report, which was calulated using a life-table method using national estimates from 2001-10. Age-specific prevalence of thyroid cancer was estimated using the cumulative risk from 2010. The annual percent change of increasing cases of thyroid cancer was taken into account as well.

This study would be useful because it shows the prevalence of overdiagnosis. It shows that while the nuclear disaster did cause an increase in the observed thyroid cancers, this was well above the expected number of cases. While they did not present the dangerous implications of overdiagnosis, this is something that could be researched further. It can be considered a good thing that these cases were found through the Program put in place, but can also cause harm if unnecessary radiation was administered.
