Which part of the breast has the most mobile margins?

The inferior and lateral aspects of the breast are known to have the most mobile margins due to their anatomical structure and position. These areas are less tethered compared to other segments of the breast, allowing for greater movement during physical examination or imaging procedures. The tissue density and the anatomical features in this region contribute to this mobility.

In contrast, the medial aspect tends to be more stable because it is closer to the thoracic wall and may be anchored by surrounding structures. Similarly, the superior aspect is less mobile compared to the inferior and lateral areas due to the presence of connective tissue and ligaments that provide support. The central portion of the breast, which typically contains more glandular tissue, also has less mobility than the inferior and lateral aspects because of its connection to other breast structures.

Understanding the anatomy and mobility of different breast segments is crucial in mammography and clinical examinations, as it influences the approach to imaging and the interpretation of results.
