Medical Intelligence & Overview
Non-Hodgkin lymphoma (NHL) is a type of cancer that originates in the lymphatic system, part of the body's immune system. When the exact type or location of the lymphoma cannot be specified, it is categorized under 'unspecified' with the ICD-10 code C85.9. This condition involves abnormal growth of lymphocytes, a type of white blood cell, which can form tumors in lymph nodes and other organs.
Causes & Symptoms
Clinical Causes: Genetic mutations that affect lymphocyte growth and function Certain infections such as the Epstein-Barr virus or Helicobacter pylori Immune system deficiencies or suppression (e.g., from medications or HIV/AIDS) Exposure to specific chemicals or substances like pesticides, solvents, or radiation Age-related factors, with increased risk as people get older
Key Symptoms: Swollen lymph nodes, often painless, in the neck, armpit, or groin Unexplained fevers and chills Unintended weight loss Persistent fatigue and weakness Night sweats Itching skin Persistent cough or trouble breathing if the chest lymph nodes are involved Abdominal pain or swelling due to enlarged spleen or liver
Diagnostic & Treatment
Diagnosis Path: Biopsy of an enlarged lymph node or affected tissue to examine the cells Imaging tests such as CT scans, PET scans, or MRI to identify the location and extent of the disease Blood tests to assess overall health and detect abnormal cells Bone marrow biopsy to check if the lymphoma has spread to the bone marrow
Treatment Protocols: Chemotherapy, which uses drugs to kill cancer cells Radiation therapy to target localized areas of lymphoma Targeted therapy that interferes with specific molecules involved in cancer growth Immunotherapy to boost the body's natural defenses against cancer Stem cell or bone marrow transplant in certain cases Clinical trials exploring new therapies
