Non-Hodgkin Lymphoma

Non-Hodgkin lymphoma (NHL) is a group of blood cancers that originate from lymphocytes, a type of white blood cell, and typically develop in the lymphatic system, which is acquired rather than inherited. It is the sixth most common cancer in adults and encompasses various subtypes, including T-cell non-Hodgkin lymphoma, which arises from T-cell lineage. The most frequent sign is painless enlargement of lymph nodes, commonly found in the neck, armpits, or groin, though swollen lymph nodes can occur due to other conditions as well. Additional symptoms may include fever, drenching night sweats, unexplained weight loss, and fatigue. NHL can affect lymphatic tissue in organs such as the stomach and intestines, and it differs significantly from Hodgkin lymphoma in its cellular characteristics and clinical presentation. Early recognition of these symptoms is crucial for timely diagnosis and effective treatment.
