Lung Cancer Rates
New Cases:
- The rate of new lung cancer cases in Illinois is 57.2 and significantly higher than the national rate of 52.1.
- It ranks 33rd among all states, placing it in the average tier.
- Over the last five years, the rate of new cases in Illinois improved by 6%.
- Note: When examining incidence data, it is important to note that the COVID-19 pandemic disrupted access to medical care. This resulted in a drop in cancer diagnoses for the year 2020, particularly for cancers diagnosed before symptoms develop (including lung cancer). This drop reflects changes in medical care for 2020 and should not necessarily be interpreted as a reduction in the underlying cancer burden.

Summary
Despite the early diagnosis rate in Illinois falling into the average tier, the state still has a lot of work to do to make sure that more of those at high risk for lung cancer are screened.
Illinois was one of the states that required insurance coverage of comprehensive biomarker testing, which can help determine what treatment options would be best for individuals with lung cancer and other diseases.
Illinois falls into the above average tier for percent of patients receiving no treatment. Some patients do refuse treatment, but issues such as fatalism and stigma can prevent eligible patients from accessing treatment that may save or extend their lives. All patients should work with their doctors to establish a treatment plan and goals.
