They are located in the upper outer quadrant of the axilla and are grouped together in clusters. The axillary lymph nodes are small, bean-shaped structures that are typically less than 1cm in diameter. They are embedded in a network of connective tissue and blood vessels, and are surrounded by a thin layer of fat.The axillary lymph nodes are an important part of the body's immune system, as they help to filter out and remove waste and toxins from the surrounding tissues. They also play a crucial role in the body's response to infection and disease. When an infection or injury occurs in the arm or chest area, the axillary lymph nodes will swell and become tender as they work to remove the invading organisms.The axillary lymph nodes are also important in the detection and staging of certain types of cancer, such as breast cancer. When a malignant tumor develops in the breast, it can spread to the axillary lymph nodes through the lymphatic vessels.
