Description: Lymphadenopathy refers to the swelling of lymph nodes, which are small bean-shaped structures that are part of the body’s immune system. These nodes act as filters to trap viruses, bacteria, and other harmful substances, and their swelling can be a sign that the body is fighting an infection or disease. Lymphadenopathy can be localized, affecting a specific group of nodes, or generalized, involving multiple areas of the body. The swelling can be painful or painless and may be accompanied by other symptoms such as fever, night sweats, or weight loss. It is important to note that lymphadenopathy is not a disease in itself but a symptom that can be associated with various conditions, ranging from common infections to more serious diseases like lymphomas or leukemias. Medical evaluation is crucial to determine the underlying cause of lymphadenopathy and establish appropriate treatment.
