Which benign breast lesion is characterized by overgrowth of glandular tissue and ducts?

The correct response highlights Fibroadenoma as the benign breast lesion characterized by an overgrowth of glandular tissue and ducts. Fibroadenomas are solid, benign tumors made up of both glandular and stromal (connective) tissues. This mixture results in a well-circumscribed, mobile mass that feels firm or rubbery upon examination. Their composition primarily includes glandular elements, which relates directly to the question’s focus on overgrowth.

In contrast, Gynecomastia refers to the enlargement of male breast tissue due to hormonal changes and is not classified as a lesion in the same way. Intraductal Papilloma consists of small, finger-like projections within the ducts of the breast and may lead to discharge, but does not embody the general overgrowth of glandular tissue as Fibroadenomas do. Phyllodes Tumors (also known as cystosarcoma phyllodes) are typically more complex and can exhibit varying degrees of malignancy, and while they also involve stromal components, they differ significantly from the benign nature of the classic fibroadenoma morphology.

Understanding the unique properties and characteristics of these different breast lesions is essential in clinical practice and diagnosis. This knowledge helps in differentiating between benign and potentially
