From this plexus, lymphatic drainage takes place through three main routes that parallel venous tributaries. Lymphatics from the left breast ultimately terminate in the thoracic duct and the left subclavian vein , and from the right breast in the right subclavian vein. Other pathways occur when usual channels are blocked in disease. Lymph may pass to the contralateral breast, cervical nodes, peritoneal cavity and liver through the diaphragm or through the rectus sheath.

Breast - Wikipedia
The blood from the upper limb is returned to the heart by two sets of veins, superficial and deep. Both sets have valves, and both drain ultimately into the axillary vein. Superficial Veins fig. The superficial veins are highly variable, lie mostly in the subcutaneous tissue, and return almost all of the blood.
The breasts are paired structures located on the anterior thoracic wall, in the pectoral region. They are present in both males and females, yet are more prominent in females following puberty. In females, the breasts contain the mammary glands — an accessory gland of the female reproductive system. The mammary glands are the key structures involved in lactation. In this article, we shall look at the anatomy of the breasts — their structure, innervation, vascular supply and any clinical relevance.
NCBI Bookshelf. The venous drainage of the upper extremities is again divided into a superficial and deep system. The dorsal digital veins are highly interconnected and form an array of superficial dorsal veins.
