Non-Hodgkin’s Lymphoma: Symptoms and Causes

Non-Hodgkin’s Lymphoma Symptoms: Non-Hodgkin’s Lymphoma (NHL) is a complex group of blood cancers that originates in the lymphatic system.

Unlike Hodgkin’s lymphoma, which is marked by the presence of Reed-Sternberg cells, NHL involves various types of lymphocytes, and its diagnosis can be challenging.

This disease affects the body’s immune system and has a wide array of symptoms and underlying causes, which can vary significantly from person to person.

What is Non-Hodgkin’s Lymphoma?

Non-Hodgkin’s lymphoma (NHL) is a type of cancer that originates in the lymphatic system, which is an integral part of the body’s immune system. Unlike Hodgkin’s lymphoma, which has distinct characteristics, Non-Hodgkin’s lymphoma encompasses a diverse group of blood cancers that vary significantly in their severity—from slow-growing to very aggressive forms.

Types of Non-Hodgkin’s Lymphoma and General Statistics

Non-Hodgkin’s lymphoma is categorized into several types, primarily based on the kind of lymphocyte it originates from: either B-cells or T-cells. The most common types of Non-Hodgkin’s lymphoma include:

• Diffuse large B-cell lymphoma (DLBCL): This is the most prevalent type, accounting for about 30% of all NHL cases.
• Follicular lymphoma: The second most common type, making up about 20% of all cases, typically affects older adults.
• Mantle cell lymphoma: A rarer form that usually progresses quickly.
• Peripheral T-cell lymphoma: This group of aggressive diseases represents a minority of lymphomas.

In terms of general statistics, NHL affects over 500,000 people worldwide each year, with new cases increasing due to factors like aging populations and better diagnostic techniques. The survival rates for NHL vary widely, depending on the type, stage at diagnosis, and patient’s overall health.

Key Differences Between Hodgkin’s and Non-Hodgkin’s Lymphoma

While both Hodgkin’s lymphoma and Non-Hodgkin’s lymphoma affect the lymphatic system, they are distinguishable based on their cellular characteristics and behavior:

• Presence of Reed-Sternberg cells: Hodgkin’s lymphoma is marked by the presence of large, abnormal lymphocytes known as Reed-Sternberg cells. In contrast, these cells are not found in Non-Hodgkin’s lymphoma.
• Spread pattern: Hodgkin’s lymphoma typically progresses in an orderly manner from one lymph node group to another. Non-Hodgkin’s lymphoma, however, can spread in a less predictable manner and involve multiple lymph nodes throughout the body.
• Subtypes and variability: Non-Hodgkin’s lymphoma has many more subtypes than Hodgkin’s lymphoma, reflecting a broader range of diseases with different patterns of behavior and treatment responses.
• Incidence and age distribution: Non-Hodgkin’s lymphoma is more common and generally affects older adults, whereas Hodgkin’s lymphoma has a bimodal age distribution, typically affecting people in their 20s and again over the age of 55.

However, understanding the differences and characteristics of these lymphomas is crucial for diagnosis and determining the most effective treatment strategies.

Symptoms of Non-Hodgkin’s Lymphoma

Recognizing the symptoms of NHL can help in timely diagnosis and treatment. Here’s a detailed guide on the common symptoms, their manifestations, differentiation from other illnesses, and when to seek medical advice.

Common Symptoms of Non-Hodgkin’s Lymphoma

1. Swollen Lymph Nodes: One of the most notable signs of NHL is painless swelling of the lymph nodes in the neck, armpits, or groin. These swellings are typically soft, rubbery, and may increase in size over time.
2. Fever: Unexplained fevers that persist and cannot be attributed to common infections are a recurring symptom in individuals with NHL.
3. Night Sweats: Profuse sweating during the night, often to the point that it drenches bedclothes, is a common symptom of NHL.
4. Unintended Weight Loss: Losing weight rapidly without changes to diet or exercise routines can be a sign of NHL.
5. Fatigue: Persistent fatigue that does not improve with rest may indicate NHL, as the body’s resources are diverted to fighting the cancer.
6. Itchy Skin: Severe and unexplained itching (pruritus) can occur, often without an accompanying rash.
7. Cough or Breathlessness: Enlarged lymph nodes in the chest area can press against the windpipe or lungs, leading to a cough or shortness of breath.

How These Symptoms Manifest and What Causes Them

The symptoms of NHL typically manifest due to the abnormal proliferation of lymphocytes (a type of white blood cell) that accumulate in the lymph nodes and other parts of the lymphatic system. This accumulation can cause the lymph nodes to enlarge and disrupts the normal function of the immune system. The exact causes of NHL are not well understood but involve genetic mutations and possible environmental factors.

Signs That Differentiate NHL from Other Illnesses

NHL might initially mimic symptoms of more common infections or inflammatory diseases, such as the flu or mononucleosis. However, the persistence of symptoms like painless lymph node swelling, unexplained fevers, night sweats, and significant weight loss without cause are more indicative of NHL than typical benign conditions. Additionally, NHL symptoms generally do not respond to standard treatments for infections or inflammation.

When to Seek Medical Advice

It’s important to seek medical advice if you experience:

• Swollen lymph nodes that are painless and persist for more than a few weeks.
• Unexplained fever, night sweats, and significant weight loss.
• Persistent fatigue or new, unexplained symptoms that do not respond to general care.

If you or someone you know is experiencing these symptoms, contacting a healthcare provider for a thorough evaluation is advised.

Causes and Risk Factors of Non-Hodgkin’s Lymphoma

Understanding the causes and risk factors associated with this disease is essential for awareness and potentially reducing the risk of developing NHL. While the exact causes of NHL remain unclear, several risk factors have been identified.

Causes of Non-Hodgkin’s Lymphoma

Non-Hodgkin’s lymphoma arises from mutations in the lymphocytes, a type of white blood cell that plays a vital role in the immune system. These mutations cause cells to multiply uncontrollably, accumulating and forming tumors throughout the lymphatic system. The exact trigger for these mutations is not well-understood, but several factors may increase the risk.

List of Risk Factors for Non-Hodgkin’s Lymphoma

1. Age: The risk of developing NHL increases with age, most commonly affecting individuals over 60.
2. Immune System Deficiency: Individuals with weakened immune systems, whether from inherited conditions, autoimmune diseases, HIV/AIDS, or medications that suppress immune function, are at a higher risk.
3. Exposure to Chemicals: Certain chemicals, particularly those involved in agriculture and pest control, such as pesticides and herbicides, may increase the risk.
4. Radiation Exposure: Exposure to high levels of radiation, either from radiation therapy for other cancers or from environmental sources, can increase the risk of developing NHL.
5. Infections: Some viral and bacterial infections that alter immune function can increase the risk. These include Epstein-Barr virus, Helicobacter pylori, and human T-cell leukemia/lymphoma virus (HTLV-1).
6. Genetic Factors: Although rare, familial patterns of NHL suggest that genetic factors may play a role in some cases.

Is Non-Hodgkin’s Lymphoma Preventable?

Preventing Non-Hodgkin’s lymphoma can be challenging since many of its risk factors, such as age and genetic predisposition, are not modifiable. However, minimizing exposure to known environmental risks like pesticides and practicing infection prevention can help reduce risk. It’s also important for individuals with weakened immune systems to have regular medical check-ups that might detect early signs of NHL. Awareness and proactive health measures can be crucial in managing the risk associated with this disease.

By understanding the risk factors and discussing preventive measures, individuals can take informed steps toward reducing their likelihood of developing Non-Hodgkin’s lymphoma, even though it is not entirely preventable.
