If you have breast cancer, your breast health specialist should discuss lymph nodes with you. Here is a bit of information about lymph nodes. The lymph (lymphatic) system of the breast is important to understand because it is one way breast cancers can spread. This system has several parts. Lymph nodes are small, bean-shaped collections of immune system cells (cells that are important in fighting infections) that are connected by lymphatic vessels. Lymphatic vessels are like small veins, except that they carry a clear fluid called lymph (instead of blood) away from the breast. Lymph contains tissue fluid and waste products, as well as immune system cells. Breast cancer cells can enter lymphatic vessels and begin to grow in lymph nodes. Most lymphatic vessels in the breast connect to lymph nodes under the arm ( axillary nodes ). Some lymphatic vessels connect to lymph nodes inside the chest ( internal mammary nodes ) and those either above or below the collarbone ( supraclavicular or infraclavicular nodes ). If you are diagnosed with breast cancer, your Breast Health Specialist will examine lymph nodes to check for spread of breast cancer.
