Ethylene Oxide (or EtO) is a human carcinogen that has been shown to cause cancers of the white blood cells, including non-Hodgkin lymphoma, myeloma, and lymphocytic leukemia.

The EPA’s National Air Toxics Assessment (NATA) study found a high concentration of ethylene oxide in Lakewood, CO. Additionally, the Colorado Department of Public Health and Environment (CDPHE) conducted air monitoring tests for ethylene oxide that also revealed that residents are at an increased risk of cancer. The test found that Terumo’s EtO emissions in one location near the facility were associated with an excess cancer risk of up to 5,652 cases per million people—over 56 times the EPA’s acceptable limit and more than 188 times the background national average.

The alleged source of the EtO contamination is the Terumo BCT facility in Lakewood, CO. Terumo uses EtO in its commercial medical sterilization process. When Terumo uses EtO, large amounts of the chemical are released out of the facility and into the community.

Although Terumo reduced its emissions and installed EtO emission controls at its facility, individuals living and working near the facility may still have an increased risk of cancer(even after Terumo installed its emission controls).

Edelson PC is filing ethylene oxide exposure lawsuits on behalf of workers and nearby residents who have been diagnosed with cancer. If you live or work in Lakewood, CO and have a recently confirmed cancer diagnosis, you may qualify for a lawsuit. Contact us for a free, no-obligation case review.

Have you ever lived or worked in this area? Your cancer may have been caused by EtO emissions.

Recognizing Ethylene Oxide Exposure


Short term inhalation of high concentrations of EtO can cause headache, dizziness, nausea, fatigue, respiratory irritation (e.g., coughing, shortness of breath, wheezing) and, in some cases, vomiting and other types of gastrointestinal distress.

The greatest risk is for people who live, have lived, or work near a facility releasing EtO into the air. Long-term exposure to Ethylene Oxide increases the risk of cancers of the white blood cells, including non-Hodgkin lymphoma, myeloma, and lymphocytic leukemia. Additionally, brain tumors are among the types of tumors observed in individuals exposed to EtO. Studies also show that long-term exposure to Ethylene Oxide increases the risk of breast cancer in females.

Animal studies have shown that breathing Ethylene Oxide at high levels can interfere with their ability to reproduce and has caused developmental issues in their offsprings.
