Overview

Breast tissue contains glandular lobules ducts and supporting stroma that produce and transport milk. The breast overlies the pectoral muscles and extends from the clavicle to the inframammary fold. Hormonal influences drive development and lactation.

Glandular and Ductal Structure

Lobules produce milk and drain into lactiferous ducts that open at the nipple. Fibrous and fatty stroma provide structural support and vary with age and hormonal status. Imaging evaluates density and focal lesions.

Lymphatic Drainage

Breast lymphatics drain primarily to axillary nodes and to internal mammary nodes. Nodal status is critical for staging breast cancer and planning treatment. Sentinel node biopsy and imaging guide management.

Clinical Relevance

Breast imaging includes mammography ultrasound and MRI for screening diagnosis and staging. Benign and malignant lesions require tissue diagnosis and multidisciplinary care. Early detection improves breast cancer outcomes.
