High cancer rates In September 2018, the Illinois Department of Public Health began a cancer incidence study based on the recommendation of the Agency for Toxic Substances and Disease Registry. The Willowbrook area shows a '300 in a million' cancer risk based on the 2014 National Air Toxics Assessment, far higher than neighboring communities with a '40 in a million' cancer incidence. A local facility, Sterigenics International, Inc., uses a 'probable carcinogen' called Ethylene Oxide to sterilize medical equipment. According to the EPA fact sheet, 'Long-term exposure to ethylene oxide can irritate the eyes, skin, nose, throat, and lungs, and harm the brain and nervous system (causing effects such as headaches, memory loss, numbness). Studies show that breathing air containing elevated ethylene oxide levels over many years increases the risk of some types of cancers, including cancers of the white blood cells (such as non-Hodgkin's lymphoma, myeloma and lymphocytic leukemia); and breast cancer in females.' On September 30, 2019 Sterigenics announced the closing of the Willowbrook facility eliminating key source of cancer causing chemical.
