👉 The breast veins are small blood vessels that run beneath the skin and connect to larger veins in the chest wall or abdomen. They are responsible for draining blood from the breast tissue back to the heart. Unlike the larger milk ducts, breast veins are often more visible as they tend to be thinner and more superficial. They can become swollen or filled with fluid during pregnancy or after breast surgery, leading to conditions like pectoral vein engorgement.
