lymph node involvement

Lymph node involvement refers to the presence of cancer cells in the lymph nodes, which are small structures in the immune system that help fight infections and diseases. When cancer spreads from its original site, it often travels to nearby lymph nodes. Doctors examine these nodes to determine how advanced the cancer is, which influences treatment options and prognosis. If the lymph nodes are affected, it may indicate that the cancer is more aggressive. Monitoring lymph node involvement is crucial in cancer staging, helping guide treatment decisions and providing insight into patient outcomes.
