Today more men and women die from lung cancer than any other type of cancer. The disease claims the lives of more than 160,000 Americans each year. In the United States, adenocarcinoma, which originates in epithelial cells, is the most common form of lung cancer. Similar to other lung cancers, the development of adenocarcinoma is often linked with smoking tobacco products.
