Adenocarcinoma of the lung is a form of non-small cell lung cancer. Eighty percent of lung cancers are non-small cell cancers, and of these, about 50% are adenocarcinomas.
Adenocarcinoma of the lung begins in the outer parts of the lung, and it can be present for a long time before it is diagnosed. It is the type of lung cancer most commonly seen in women and is often seen in non-smokers.
Treatments for adenocarcinoma include surgery, chemotherapy, and radiation therapy, but targeted therapies -- therapies that attack lung cancer cells specifically -- are both approved and being tested in clinical trials for this type of lung cancer.
