Glandular tissue is a type of tissue that produces and releases substances like mucus, digestive juices, and other bodily fluids. It lines many internal organs and plays a vital role in various bodily functions.
Location and Function
Glandular tissue is found in numerous locations throughout the body, including:
- Breast: Glandular tissue is a significant component of the breast, along with fibrous and fatty tissue. The relative amount of glandular tissue compared to fatty tissue influences breast density, a factor relevant in breast cancer screening. (Breast Cancer | CDC, Dense Breast Tissue | Breast Density and Mammogram Reports)
- Lungs: Glandular tissue contributes to the structure and function of the lungs.
- Stomach, Colon, Pancreas: These digestive organs heavily rely on glandular tissue for secretion of digestive enzymes and other substances.
- Prostate, Uterus, Cervix: These reproductive organs utilize glandular tissue for various functions including hormone production.
The types of substances released by glandular tissue are diverse and tailored to the organ's function. These substances can be hormones (released directly into the bloodstream by endocrine glands) or other fluids secreted through ducts (exocrine glands). (Glandular tissue: The Histology Guide)
Glandular Tissue and Cancer Risk
The amount of glandular tissue in the breast, relative to fatty tissue, is a factor considered in breast cancer risk assessment. Higher glandular tissue density is associated with a slightly elevated risk. (Glandular Tissue Component and Breast Cancer Risk in ...)
Further Considerations
The term "glandular tissue" is often used interchangeably with "glandular epithelium," which refers to the epithelial cells forming the glands. (Glandular Epithelium: What Is It, Location, Functions, and More ..., Definition of glandular epithelium - NCI Dictionary of Cancer Terms ...) The relative proportion of glandular tissue to other tissue types (such as fibrous and fatty tissue) is crucial in various medical contexts, particularly in radiology and oncology.
