Adenocarcinoma of the Lung

What Is It?

Adenocarcinoma of the lung is a type of lung cancer. It occurs when abnormal lung cells multiply out of control and form a tumor. Eventually, tumor cells can spread (metastasize) to other parts of the body including the

  • lymph nodes around and between the lungs

  • liver

  • bones

  • adrenal glands

  • brain.

Compared with other types of lung cancer, adenocarcinoma is more likely to be contained in one area. If it is truly localized, it may respond to treatment better than other lung cancers.
