How Non-Small Cell Lung Cancer Is Treated

When you breathe, air flows down your trachea, through your bronchi, and into your lungs. When a person develops non-small cell lung cancer (NSCLC), it usually (though, not always) begins within the bronchi. Once it forms, the cancer generates chemicals that help produce new blood vessels, which in turn feed the cancerous cells. This process results in the formation of a tumor. Eventually, the tumor grows until it can be identified through an x-ray. Meanwhile, the cancerous cells metastasize and become more difficult to treat.
