Adenocarcinoma is a type of lung cancer that develops in the cells that line the lungs’ air sacs and glands. It is the most common type of lung cancer and accounts for about 40% of all cases.

Adenocarcinomic lung tissue refers to lung tissue that has been diagnosed with adenocarcinoma. The tissue may be obtained through a biopsy or surgical procedure and is then examined by a pathologist to confirm the diagnosis and determine the cancer’s stage and grade.

Treatment for adenocarcinoma of the lung may include surgery, radiation therapy, chemotherapy, or targeted therapy, depending on the cancer’s stage and other factors. The prognosis for adenocarcinoma of the lung can vary widely depending on the cancer’s stage and the patient’s overall health. Early detection and treatment can improve the chances of successful treatment and long-term survival.
