area. Louisiana Chemical Association President Greg Bowser responded to President Biden's remarks on the region, refuting claims that residents of the industrial corridor have a higher risk of developing cancer in multiple articles. Furthermore, he cited Louisiana Tumor Registry (LTR) data to support his claims. The LTR shows that there have not been an increase in cancer deaths connected to industrial pollution. Activists and locals have combated the LTR. Activists claim the census tracts utilized for the LTR cover large areas and the data does not allow for specific locations next to chemical plants to be viewed individually. Moreover, the registry relies on medical records to distinguish if cancer was the cause of death. Locals are concerned that COVID-19 deaths will not attribute statistically to cancer if the victims were suffering from it. Another statistical concern for locals is that people will not seek medical help before they die because of monetary or social reasons. Louisiana health officials may not release the specific cases and data because of medical privacy laws. Cancer studies In their 2012 book Petrochemical America, photographer Richard Misrach and Columbia University architecture professor Kate Orff explore the social, environmental, and health impacts of the petrochemical industry in Cancer Alley through photography, writing, and infographic-style illustrations. Cancer Alley was previously called Chemical Corridor before residents and environmental health experts claimed it was a hotbed of cancer activity. However, 50 toxic chemicals were found in the air in the area, including benzene, formaldehyde, and ethylene oxide. One of the most concerning chemicals in the area is chloroprene, which according to the Environmental Protection Agency (EPA), is likely to cause cancer. It was not until the late 1980s when the residents of the area began to notice clusters of cancer cases and miscarriages within a few miles of each other that they started to call the area Cancer Alley. Research has shown that there are abnormally high amounts of lung, stomach, and kidney cancer among certain populations that live in Cancer Alley. There have also been cases of more rare cancers in the area like neuroblastoma, cancer of the nerve cells, and rhabdomyosarcoma, cancer of the skeletal muscle. Lung cancer is one of the most common cancers in the area because of the prevalence of industries that produce iron/steel, rubber, paint, aluminum, and other chemicals.
