🔬 Medical science
Lymph nodes filter lymph and host immune cells that fight infection. They commonly enlarge reactively during infections; persistent or hard nodes can signal lymphoma or metastatic cancer.
Diagnosis uses examination, imaging and biopsy; lymphoma is treated with chemotherapy, immunotherapy and radiotherapy, often with high cure rates.
🧩 The GNM model
Claimed conflict: GNM links the lymph nodes to a "self-devaluation conflict" affecting the corresponding body region.
Germ layer & brain relay (GNM model): GNM classes lymph nodes as new mesoderm controlled from the cerebral medulla.
Two-phase course (claimed): GNM claims the node loses tissue during the conflict-active phase and swells during the healing phase — and (controversially) treats lymphoma as a healing-phase event.
