Some women's breasts have varying proportions of glandular tissue than of adipose or connective tissues. Adenocarcinoma is a cancer of epithelial tissue that has glandular characteristics. The breasts are principally composed of adipose, glandular, and connective tissues. They lie between the basement membrane and glandular epithelium. It consists of glandular and stroma tissue from the lining of the uterus. If chronic gynecomastia is untreated, surgical removal of glandular breast tissue is usually required. The pharynx opens into a cylindrical intestine, which is lined with glandular and digestive cells. This kin recognition is by olfactory cues from urine, feces and glandular secretions.
