Non-Hodgkin's Lymphoma: Symptoms, Causes, Diagnosis, and Treatment | AIROC Hospitals

About Non-Hodgkin's Lymphoma – Overview and Types

Non-Hodgkin's lymphoma (NHL) is a diverse group of cancers that begin in the lymphatic system, developing when white blood cells called lymphocytes grow and multiply abnormally. It is the more common of the two major lymphoma categories and encompasses a wide range of subtypes that differ significantly in how they behave and respond to treatment. At AIROC Hospitals, our hematology-oncology specialists provide detailed subtype classification and individualized treatment planning to manage NHL effectively, from slow-growing forms to more aggressive disease.

Unlike Hodgkin's lymphoma, which is identified by the presence of a specific abnormal cell, non-Hodgkin's lymphoma includes many distinct subtypes with different growth patterns, treatment approaches, and outcomes. This diversity makes precise diagnosis especially important, and our team at AIROC Hospitals places strong emphasis on thorough pathological evaluation for every patient.

Types of Non-Hodgkin's Lymphoma

NHL is broadly classified based on the type of lymphocyte involved and how quickly the cancer grows:

• B-Cell Lymphomas – The most common category, accounting for the majority of NHL cases, including subtypes such as:
• Diffuse Large B-Cell Lymphoma (DLBCL) – The most common aggressive subtype, growing quickly but often responding well to treatment.
• Follicular Lymphoma – A common slow-growing (indolent) subtype that may not require immediate treatment.
• Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma (CLL/SLL) – A slow-growing subtype closely related to a type of leukemia.
• Mantle Cell Lymphoma – A less common subtype that can behave more aggressively.
• Burkitt Lymphoma – A rare but highly aggressive subtype requiring prompt, intensive treatment.
• T-Cell Lymphomas – A less common category, including subtypes such as peripheral T-cell lymphoma and cutaneous T-cell lymphoma, which can vary widely in behavior.

Because treatment approaches differ significantly between subtypes, our specialists at AIROC Hospitals conduct detailed pathological and genetic testing to identify the precise subtype and guide the most effective treatment plan.

 

Symptoms and Causes

Common Symptoms of Non-Hodgkin's Lymphoma

Symptoms of NHL can vary depending on the subtype and location involved, but commonly include:

• Painless swelling of lymph nodes in the neck, underarm, or groin
• Persistent fatigue
• Unexplained fever
• Drenching night sweats
• Unintentional weight loss
• Abdominal pain or swelling, if the spleen or abdominal lymph nodes are affected
• Chest discomfort, cough, or shortness of breath, if lymph nodes in the chest are involved
• Skin changes or rashes, particularly with certain T-cell lymphoma subtypes
• Loss of appetite

Because swollen lymph nodes are often caused by infections, persistent swelling lasting several weeks — particularly alongside other symptoms — should be evaluated by a specialist.

Causes and Risk Factors

The exact cause of non-Hodgkin's lymphoma is not fully understood, but several factors are known to increase risk:

• Weakened Immune System: Conditions that suppress immune function, including certain infections and immunosuppressive medications, increase risk.
• Viral and Bacterial Infections: Epstein-Barr virus, HIV, hepatitis C, and Helicobacter pylori infection have been linked to specific NHL subtypes.
• Autoimmune Conditions: Diseases such as rheumatoid arthritis, lupus, and celiac disease are associated with a higher risk of developing certain lymphomas.
• Age: Risk generally increases with age, with most cases diagnosed in adults over 60.
• Family History: Having a close relative with lymphoma may modestly increase individual risk.
• Exposure to Certain Chemicals: Long-term exposure to pesticides, herbicides, or industrial chemicals has been linked to increased risk in some studies.
• Previous Cancer Treatment: Prior chemotherapy or radiation therapy for another cancer can increase the risk of developing NHL later in life.

Understanding these risk factors helps our team at AIROC Hospitals guide appropriate evaluation, particularly for patients with relevant medical history.

 

Diagnosis and Treatment

How Non-Hodgkin's Lymphoma Is Diagnosed

At AIROC Hospitals, we use a thorough diagnostic approach to confirm NHL and determine its exact subtype and stage:

• Physical Examination: Checking for swollen lymph nodes and an enlarged spleen or liver.
• Lymph Node Biopsy: The definitive test, in which a sample of lymph node tissue is examined to identify the specific subtype of lymphoma.
• Blood Tests: Used to assess overall health and detect abnormalities that may indicate lymphoma.
• Imaging Tests: CT, PET, and MRI scans help determine the extent and spread of the disease.
• Bone Marrow Biopsy: Performed to check whether the lymphoma has spread to the bone marrow.
• Molecular and Genetic Testing: Helps identify specific subtypes and guide targeted treatment decisions, which is particularly important given the diversity of NHL.

Treatment Options at AIROC Hospitals

Treatment for non-Hodgkin's lymphoma is highly individualized based on subtype, stage, and overall health, and may include:

• Watchful Waiting: For slow-growing lymphomas without symptoms, careful monitoring may be recommended before starting treatment.
• Chemotherapy: A cornerstone treatment for many NHL subtypes, often using a combination of drugs to target cancer cells throughout the body.
• Immunotherapy: Includes antibody-based treatments that help the immune system recognize and destroy lymphoma cells, commonly combined with chemotherapy.
• Radiation Therapy: Used alone for localized disease or combined with chemotherapy for more extensive involvement.
• Targeted Therapy: Drugs designed to act on specific molecular features of certain NHL subtypes.
• Stem Cell Transplant: Considered for relapsed or treatment-resistant lymphoma, using high-dose therapy followed by transplantation of healthy stem cells.
• CAR T-Cell Therapy: An advanced treatment option for certain relapsed or refractory B-cell lymphomas, using genetically modified immune cells to target cancer.

Our multidisciplinary team at AIROC Hospitals — including hematologists, radiation oncologists, and transplant specialists — works closely together to design a treatment plan tailored to each patient's specific NHL subtype.

 

Prevention and Risk Factors

Because the exact cause of non-Hodgkin's lymphoma remains unclear and many risk factors, such as age and genetics, cannot be changed, there is currently no established way to prevent it directly. However, the following can support early detection and overall health:

• Awareness of Persistent Symptoms: Painless, persistent lymph node swelling, unexplained fevers, or night sweats should never be ignored.
• Prompt Medical Evaluation: Early diagnosis allows for timely treatment, which is particularly important for aggressive NHL subtypes.
• Managing Underlying Conditions: Appropriate treatment of chronic infections and autoimmune conditions may help reduce associated risk.
• Limiting Exposure to Harmful Chemicals: Taking precautions in occupational settings with known risk substances such as pesticides and herbicides.
• Monitoring After Previous Cancer Treatment: Individuals with a history of chemotherapy or radiation therapy should maintain regular follow-up care.

At AIROC Hospitals, we emphasize the importance of timely evaluation for persistent lymph node swelling or unexplained systemic symptoms, as early diagnosis plays a key role in successfully treating non-Hodgkin's lymphoma across its many subtypes.
