Checking lymph nodes is a self-exam technique used to detect any abnormalities or changes in the lymph nodes, which are small, bean-shaped structures in the lymphatic system that help fight infection and disease.
Regularly checking lymph nodes is important because it allows individuals to monitor their health and potentially detect early signs of certain medical conditions, such as infection or cancer. By becoming familiar with the normal size, shape, and texture of their lymph nodes, individuals can more easily identify any changes that may warrant further medical evaluation.
