Thyroid Cancer Symptoms: Swollen Lymph Nodes
Gland swelling commonly refers to enlargement of the lymph glands, also known as lymph nodes. Lymph nodes are small rounded or bean-shaped masses of lymphatic tissue surrounded by a capsule of connective tissue. Lymph glands (nodes) are located in many places in the lymphatic system throughout the body. Lymph nodes filter the lymphatic fluid and store special cells that can trap cancer cells or bacteria that are traveling through the body in the lymph fluid. The lymph nodes are critical for the body's immune response and are principal sites where many immune reactions are initiated.
Swelling of the lymph glands is typically a result of local or widespread inflammation, but sometimes enlarged lymph nodes are due to cancer. Swollen lymph glands are referred to as lymphadenopathy. Inflammation of a lymph node is referred to as lymphadenitis.
Symptoms of swollen lymph nodes include:
- localized pain,
- warmth in the involved area.
