75% of the lymph from the mammary gland drains into which lymph nodes?

Explanation:
Lymph drainage from the breast is dominated by the axillary pathway. About three-quarters of the lymph from the breast travels to the axillary lymph nodes, especially the central and apical groups, making this the main drainage route. The remaining lymph drains to the parasternal (internal thoracic) nodes along the sternum, with only smaller portions going to other nodes. Because of that distribution, the axillary nodes account for the majority of drainage, while inguinal or pelvic nodes are not typical primary routes for breast lymph.
