Clinical Information

Non-Hodgkin’s lymphoma is a heterogeneous group of lymphoid malignancies that arise from B or T lymphocytes. It can manifest in various forms, including diffuse large B-cell lymphoma, follicular lymphoma, and mantle cell lymphoma, among others.


The exact cause of non-Hodgkin’s lymphoma is not fully understood, but it is believed to be a combination of genetic, environmental, and immunological factors. Risk factors for developing the disease include age, family history, immune system deficiencies, and certain infections.


The symptoms of non-Hodgkin’s lymphoma can vary depending on the type and location of the cancer, but common signs include enlarged lymph nodes, fever, night sweats, unexplained weight loss, and fatigue. Some patients may also experience itching, shortness of breath, and pain or swelling in the abdomen.


Diagnosing non-Hodgkin’s lymphoma typically involves a combination of physical exams, imaging tests, blood tests, and biopsies. A definitive diagnosis is made by examining lymph node or tissue samples under a microscope to identify abnormal lymphocytes.


Treatment for non-Hodgkin’s lymphoma depends on the type and stage of the cancer, as well as the patient’s overall health. Common treatment options include chemotherapy, radiation therapy, immunotherapy, stem cell transplantation, and targeted therapy. The goal of treatment is to achieve remission and improve the patient’s quality of life.


Non-Hodgkin’s lymphoma is a complex and diverse group of cancers that affect the lymphatic system. Proper diagnosis and treatment are essential for managing the disease and improving patient outcomes.
