State of Lung Cancer: Indiana Struggles with Early Diagnosis, Showcasing the Need for Increased Lung Cancer Screening

Today, the American Lung Association in Indiana released the 2025 “State of Lung Cancer” report, which reveals that more needs to be done to end the burden of this devastating disease on families throughout the state. Lung cancer is the leading cause of cancer deaths here in Indiana and across the U.S. The report finds that Indiana ranks 39th in the nation for early diagnosis, at 26.8%. Nationally, only 28.1% of cases are diagnosed at an early stage when the survival rate is much higher.

The Lung Association’s eighth annual “State of Lung Cancer” report highlights how the toll of lung cancer varies by state and examines key indicators throughout the U.S., including new cases, survival, early diagnosis, surgical treatment, lack of treatment, screening rates and insurance coverage of comprehensive biomarker testing.

The report found that Indiana ranks:

• 46 out of 51 in the nation for rate of new lung cancer cases, at 67.2 per 100,000. The national rate is 52.8 per 100,000.
• 39 out of 50 in the nation for early diagnosis, at 26.8%. Nationally, only 28.1% of cases are diagnosed at an early stage when the survival rate is much higher.
• 18 out of 51 in the nation for lung cancer screening, at 19.4%. Lung cancer screening with annual low-dose CT scans for people at high risk can reduce the lung cancer death rate by up to 20%. Nationally, only 18.2% of people at high risk were screened.
• 37 out of 49 in the nation for surgery as first course of treatment, at 16.9%. Lung cancer can often be treated with surgery if it is diagnosed at an early stage and has not spread. Nationally, 20.7% of cases underwent surgery.
• 17 out of 49 in the nation for lack of treatment, at 18.7%. Nationally, 21% of cases receive no treatment.
• 39 out of 51 in the nation for smoking, at 14.5%.

“In the last decade, we have seen incredible progress, including increases in lung cancer survival and early detection rates. This means that more people in Indiana are living longer after a lung cancer diagnosis,” said Tiffany Nichols, director of advocacy for the American Lung Association. “While this progress gives us hope, early detection of lung cancer is far too low in our state. Working to increase awareness and access to lung cancer screening is critical to saving lives. This is why the state must step in to ensure their residents have access to the best lung cancer care.”

The “State of Lung Cancer” report also examines insurance coverage of comprehensive biomarker testing across the U.S. Lung cancer biomarker testing, sometimes referred to as tumor, molecular, genomic or genetic testing, looks for changes in the tumor's DNA. The results of the test may show biomarkers that can help determine what treatment options would be best for an individual patient. Insurance coverage of biomarker testing is important for removing a cost barrier to people with lung cancer, but coverage for biomarker testing is only required in some states. The report found that Indiana does require insurance coverage of comprehensive biomarker testing.

The 2025 “State of Lung Cancer” report highlights opportunities for states to reduce the burden of lung cancer and encourages everyone to help end lung cancer. This year, the American Lung Association calls on other states to join our state in implementing policies to require insurance coverage of comprehensive biomarker testing.
