The lymphatic system is a network of vessels and tissues that helps maintain fluid balance, absorb fats, and support the immune system. Disorders of the lymphatic system can include conditions like lymphedema, which is the swelling caused by a buildup of lymph fluid, often due to surgery or injury. Other disorders may involve infections, such as lymphangitis, or cancers like lymphoma that affect lymph nodes. Symptoms of lymphatic system disorders can vary but often include swelling, pain, and increased susceptibility to infections. Diagnosis typically involves physical examinations, imaging tests, and sometimes biopsies. Treatment options may include medications, physical therapy, or surgical interventions, depending on the specific disorder.
