Quick Facts: Lung Cancer

Understanding your lungs is the first step. Here you’ll find clear, straightforward information about lung cancer and how it affects Indigenous communities.

What Is Lung Cancer

Lung cancer starts when cells in the lung grow out of control. Commercial tobacco smoke is the leading cause — it contains over 7,000 chemicals that damage the airways and small air sacs in your lungs. Over time, this damage can lead to lung cancer, COPD, and emphysema.

Indigenous Communities and Lung Cancer

American Indian and Alaska Native communities experience some of the highest rates of commercial tobacco use and lung cancer in the United States. This isn’t a reflection of tradition — it’s a consequence of colonization, targeted marketing, and systemic health disparities.

What Happens When You Quit

Your body starts healing quickly. Within 12 hours, carbon monoxide levels in your blood drop to normal. Within a few months, lung function begins to improve. The journey is different for everyone, but your lungs want to heal.

Early Detection Saves Lives

Lung cancer is most treatable when caught early — before symptoms appear. Screening exists for people at high risk, and it’s available at no cost to those who qualify.
