Adenocarcinoma

Adenocarcinoma is a type of cancer that forms in the glands, the cells that secrete substances within or out of the body. Adenocarcinoma is cancer that forms in mucus-secreting glands throughout the body. The disease may develop in many different places, but it is most prevalent in the following cancer types:
Lung cancer: Non-small cell lung cancer accounts for 80 percent of lung cancers, and adenocarcinoma is the most common type.
Prostate cancer: Cancer that forms in the prostate gland is typically an adenocarcinoma, which accounts for 99 percent of all prostate cancers.
Pancreatic cancer: Exocrine pancreatic cancer tumors are called adenocarcinomas. They form in the pancreas ducts.
Esophageal cancer: Cancer that forms in the glandular cells of the esophagus is known as adenocarcinoma. This is the most common type of esophageal cancer.
Colorectal cancer: Cancer that develops in the intestinal gland cells that line the inside of the colon and/or rectum is an adenocarcinoma. It makes up 95 percent of colon and rectal cancers.
