Non-Hodgkin’s lymphoma is a type of cancer that originates in the lymphatic system, which is part of the body’s immune defense network. This disease affects lymphocytes, a type of white blood cell that helps fight infections. Unlike Hodgkin lymphoma, non-Hodgkin’s lymphoma encompasses a diverse group of blood cancers that can develop in different parts of the lymphatic system, including lymph nodes, spleen, bone marrow, and other organs.
Understanding what is non-Hodgkin’s lymphoma and recognizing its symptoms early can be crucial for timely diagnosis and management. The condition can occur at any age, though it becomes more common as people get older. Non-Hodgkin’s lymphoma symptoms can vary widely depending on the type and location of the cancer, making awareness of potential warning signs essential for early detection.
In this comprehensive guide, we’ll explore the most common symptoms of non-Hodgkin’s lymphoma, helping you understand what to look for and when medical attention may be necessary.
1. Swollen Lymph Nodes
One of the most characteristic signs of non-Hodgkin’s lymphoma is painless swelling of the lymph nodes. These swollen nodes typically appear in the neck, armpits, or groin area and feel like firm, rubbery lumps beneath the skin. Unlike lymph nodes that swell due to common infections, these enlarged nodes usually don’t cause pain or discomfort.
The swelling occurs because cancerous lymphocytes accumulate in the lymph nodes, causing them to expand beyond their normal size. In some cases, the swollen lymph nodes may persist for weeks or even months without improvement. They typically don’t shrink after taking antibiotics, which would normally help with infection-related swelling.
Key characteristics of swollen lymph nodes in non-Hodgkin’s lymphoma include:
- Painless and firm to the touch
- Gradually increasing in size over time
- Don’t respond to typical infection treatments
- May occur in multiple locations simultaneously
- Can range from pea-sized to much larger
2. Unexplained Weight Loss
Significant, unintentional weight loss is a common symptom of non-Hodgkin’s lymphoma. Medical professionals typically consider weight loss significant when a person loses more than 10% of their body weight over a period of six months or less without trying to diet or increase physical activity.
This weight loss occurs for several reasons. The cancer cells consume large amounts of energy, altering the body’s metabolism. Additionally, the lymphoma can affect the digestive system, reducing appetite and making it difficult for the body to absorb nutrients properly. Some people also experience early satiety, meaning they feel full after eating only small amounts of food.
The weight loss associated with non-Hodgkin’s lymphoma is often accompanied by:
- Loss of appetite or decreased interest in food
- Feeling full quickly when eating
- Changes in taste or smell of food
- Difficulty maintaining muscle mass
- Progressive weakness alongside weight reduction
3. Persistent Fever
Recurring or persistent fever without an obvious infection source is another hallmark symptom of non-Hodgkin’s lymphoma. These fevers may come and go over weeks or months, often following a cyclical pattern. The body temperature typically rises above 100.4°F (38°C) but may vary in intensity.
The fever occurs because the lymphoma disrupts the immune system’s normal functioning. Cancer cells can release substances called cytokines that affect the body’s temperature regulation center in the brain. Additionally, the compromised immune system may struggle to fight off even minor infections, leading to recurrent fevers.
Characteristics of lymphoma-related fevers include:
- Occurring without clear signs of infection
- May be accompanied by chills and sweating
- Often worse in the evening or at night
- Don’t consistently respond to over-the-counter fever reducers
- May follow a cyclical pattern, appearing and disappearing regularly
4. Drenching Night Sweats
Severe night sweats, also called drenching night sweats, are a distinctive symptom of non-Hodgkin’s lymphoma. These are not ordinary sweating episodes—they’re intense enough to soak through nightclothes and bedsheets, often requiring a change of clothing or bedding during the night. They occur even when the room temperature is comfortable and appropriate for sleeping.
Night sweats in lymphoma patients are caused by the body’s response to the cancer cells and the substances they produce. The sweating is often more pronounced than what would occur with common causes like menopause or environmental factors. Many patients report waking up completely drenched and feeling cold after the sweating episode.
Important aspects of lymphoma-related night sweats:
- Severe enough to require changing clothes or sheets
- Occur repeatedly over several weeks
- Happen regardless of room temperature
- May be accompanied by fever or chills
- Can significantly disrupt sleep quality
5. Extreme Fatigue and Weakness
Profound, persistent fatigue is one of the most common and debilitating symptoms experienced by people with non-Hodgkin’s lymphoma. This isn’t ordinary tiredness that improves with rest—it’s an overwhelming exhaustion that interferes with daily activities and doesn’t significantly improve even after adequate sleep or rest.
The fatigue associated with lymphoma has multiple causes. The cancer itself demands significant energy from the body. Anemia, which often develops as the lymphoma affects bone marrow’s ability to produce red blood cells, contributes to tiredness and weakness. The body’s constant battle against the cancer cells also depletes energy reserves.
This fatigue typically presents as:
- Overwhelming tiredness not relieved by rest
- Difficulty performing routine daily tasks
- Need for frequent naps or rest periods
- Reduced physical and mental stamina
- Feeling exhausted after minimal exertion
- Difficulty concentrating or “brain fog”
6. Shortness of Breath and Chest Pain
When non-Hodgkin’s lymphoma affects lymph nodes in the chest or develops in the thymus gland, it can cause respiratory symptoms. Patients may experience shortness of breath, difficulty breathing, or chest discomfort. These symptoms occur because enlarged lymph nodes or tumor masses can press against the airways, lungs, or blood vessels in the chest.
In some cases, fluid may accumulate around the lungs (pleural effusion) or around the heart (pericardial effusion), further compromising breathing. These symptoms may worsen when lying down or during physical activity. Some people also experience a persistent cough that doesn’t improve with typical cold or allergy medications.
Respiratory symptoms may include:
- Difficulty breathing or feeling breathless
- Chest pressure or discomfort
- Persistent cough without other cold symptoms
- Wheezing or noisy breathing
- Worsening symptoms when lying flat
- Reduced exercise tolerance
7. Abdominal Pain and Swelling
Non-Hodgkin’s lymphoma can affect lymph nodes and organs in the abdomen, leading to various digestive symptoms. Patients may experience abdominal pain, bloating, or a feeling of fullness even after eating small amounts. The abdomen may appear visibly swollen or distended.
These symptoms occur when lymphoma develops in abdominal lymph nodes, the spleen, or the gastrointestinal tract itself. An enlarged spleen (splenomegaly) or liver (hepatomegaly) can create a sensation of pressure or fullness in the upper abdomen. In some cases, the lymphoma can cause intestinal blockages or affect the digestive system’s ability to function normally.
Abdominal symptoms associated with non-Hodgkin’s lymphoma include:
- Persistent or recurrent abdominal pain
- Feeling of fullness or pressure in the abdomen
- Visible swelling or bloating
- Nausea or vomiting
- Changes in bowel habits
- Loss of appetite due to abdominal discomfort
8. Skin Changes and Itching
Some people with non-Hodgkin’s lymphoma experience skin-related symptoms, ranging from persistent itching (pruritus) to visible skin changes. The itching can be widespread across the body or localized to specific areas. It’s often described as intense and may worsen at night or after bathing, significantly affecting quality of life.
In certain types of non-Hodgkin’s lymphoma, particularly cutaneous lymphomas, the cancer directly affects the skin. This can manifest as red, scaly patches, thickened areas, or bumps on the skin that may be mistaken for eczema, psoriasis, or other common skin conditions. The key difference is that these skin changes don’t respond to typical dermatological treatments.
Skin manifestations may include:
- Intense, persistent itching without visible rash
- Red, purple, or darkened patches on the skin
- Thickened or scaly areas
- Lumps or nodules under the skin
- Skin changes that don’t improve with standard treatments
- Itching that worsens at night
9. Frequent Infections
Because non-Hodgkin’s lymphoma affects the immune system, people with this condition often experience recurrent or persistent infections. The lymphoma impairs the body’s ability to produce healthy, functional lymphocytes and other immune cells, leaving patients vulnerable to bacterial, viral, and fungal infections.
These infections may occur more frequently than normal, last longer, or be more severe than expected. Common infections might include respiratory tract infections, urinary tract infections, skin infections, or oral thrush. Some patients notice that infections that would typically resolve quickly become prolonged or recurrent despite appropriate treatment.
Signs of compromised immunity include:
- Frequent colds, respiratory infections, or sinusitis
- Slow healing of cuts, wounds, or infections
- Recurrent infections in the same or different locations
- Unusual or opportunistic infections
- Infections that require longer treatment courses
- Overall feeling of being “run down” or unwell
10. Headaches and Neurological Symptoms
When non-Hodgkin’s lymphoma affects the central nervous system or when lymph nodes in the head and neck become significantly enlarged, patients may experience neurological symptoms. Headaches are among the most common complaints, but other symptoms can include confusion, difficulty concentrating, vision problems, or changes in coordination.
In rare cases, lymphoma can directly involve the brain or spinal cord, a condition called primary central nervous system lymphoma. This can cause more severe neurological symptoms including seizures, weakness in parts of the body, changes in personality or behavior, and speech difficulties. Even when the lymphoma doesn’t directly involve the brain, enlarged lymph nodes can press on nerves or blood vessels, causing pain, numbness, or tingling.
Neurological symptoms may include:
- Persistent or worsening headaches
- Difficulty with memory or concentration
- Vision changes or double vision
- Numbness or tingling in extremities
- Weakness in arms or legs
- Dizziness or balance problems
- Seizures in severe cases
Main Causes and Risk Factors
While the exact cause of non-Hodgkin’s lymphoma often remains unknown, researchers have identified several factors that may increase the risk of developing this disease. Understanding these risk factors can help with early detection, though having one or more risk factors doesn’t mean a person will definitely develop lymphoma.
Age and Gender
Non-Hodgkin’s lymphoma can occur at any age, but the risk increases as people get older. Most cases are diagnosed in people over 60 years of age. The disease is slightly more common in men than in women, though the reasons for this difference aren’t entirely clear.
Immune System Disorders
People with weakened or compromised immune systems have a significantly higher risk of developing non-Hodgkin’s lymphoma. This includes individuals with HIV/AIDS, those who have undergone organ transplants and take immunosuppressive medications, and people with autoimmune diseases such as rheumatoid arthritis, lupus, or Sjögren’s syndrome.
Infections
Certain viral and bacterial infections have been linked to increased lymphoma risk. The Epstein-Barr virus (which causes mononucleosis), human T-cell lymphotropic virus (HTLV-1), hepatitis C virus, and the bacterium Helicobacter pylori (which causes stomach ulcers) have all been associated with specific types of non-Hodgkin’s lymphoma.
Chemical and Environmental Exposures
Prolonged exposure to certain chemicals may increase the risk of developing lymphoma. These include pesticides, herbicides (particularly those containing chemicals like Agent Orange), and certain industrial solvents. People who work in agriculture or chemical manufacturing may have higher exposure to these substances.
Previous Cancer Treatment
Individuals who have previously received chemotherapy or radiation therapy for other cancers have an elevated risk of developing non-Hodgkin’s lymphoma later in life. The risk varies depending on the specific treatments received and the doses used.
Family History and Genetics
While non-Hodgkin’s lymphoma isn’t directly inherited, having a first-degree relative (parent, sibling, or child) with lymphoma or other blood cancers may slightly increase your risk. Certain genetic conditions and chromosomal abnormalities are also associated with higher lymphoma risk.
Frequently Asked Questions
What is the difference between Hodgkin and non-Hodgkin’s lymphoma?
The main difference lies in the type of abnormal cells present. Hodgkin lymphoma contains specific abnormal cells called Reed-Sternberg cells, which are not found in non-Hodgkin’s lymphoma. Non-Hodgkin’s lymphoma is actually a diverse group of blood cancers that includes many different subtypes, while Hodgkin lymphoma is a single disease entity. The treatment approaches, prognosis, and patterns of spread also differ between the two.
How is non-Hodgkin’s lymphoma diagnosed?
Diagnosis typically begins with a physical examination and medical history, followed by imaging tests such as CT scans, PET scans, or X-rays to identify enlarged lymph nodes or organs. The definitive diagnosis requires a biopsy, where a sample of lymph node tissue or affected tissue is removed and examined under a microscope by a pathologist. Blood tests, bone marrow biopsies, and other specialized tests may also be performed to determine the specific type and stage of lymphoma.
Are non-Hodgkin’s lymphoma symptoms always obvious?
No, symptoms can be subtle and may develop gradually over time. Some people have no symptoms initially and the lymphoma is discovered incidentally during medical examinations for other reasons. Others experience vague symptoms like fatigue or mild discomfort that can be easily attributed to other less serious conditions. This is why persistent or unusual symptoms should always be evaluated by a healthcare provider.
Can non-Hodgkin’s lymphoma symptoms come and go?
Yes, some symptoms of non-Hodgkin’s lymphoma can fluctuate. Swollen lymph nodes may occasionally decrease in size temporarily, and symptoms like fever and night sweats may follow cyclical patterns. However, the overall trend is typically toward persistence or worsening of symptoms over time. The intermittent nature of some symptoms can sometimes delay diagnosis, as people may dismiss them when they temporarily improve.
At what age does non-Hodgkin’s lymphoma usually occur?
While non-Hodgkin’s lymphoma can develop at any age, including in children, it becomes increasingly common with age. The median age at diagnosis is in the mid-60s. However, certain subtypes of non-Hodgkin’s lymphoma are more common in younger adults or children, while others predominantly affect older individuals.
Is non-Hodgkin’s lymphoma always fatal?
No, many people with non-Hodgkin’s lymphoma respond well to treatment and can achieve long-term remission or even be cured. The prognosis varies significantly depending on multiple factors including the specific subtype of lymphoma, the stage at diagnosis, the person’s age and overall health, and how well the lymphoma responds to treatment. Some types are considered highly treatable with excellent long-term outcomes, while others may be more challenging to manage.
Can stress cause non-Hodgkin’s lymphoma?
There is no scientific evidence that stress directly causes non-Hodgkin’s lymphoma. However, chronic stress can affect the immune system’s functioning, and some researchers are investigating whether long-term immune system changes might play a role in cancer development. The established risk factors for non-Hodgkin’s lymphoma are primarily related to immune system disorders, infections, genetic factors, and certain environmental exposures rather than psychological stress.
When should I see a doctor about these symptoms?
You should consult a healthcare provider if you experience any persistent or unexplained symptoms, particularly swollen lymph nodes that last more than two weeks, unexplained weight loss, persistent fever, drenching night sweats, or severe fatigue that interferes with daily activities. While these symptoms can be caused by many conditions other than lymphoma, it’s important to have them properly evaluated to determine the cause and receive appropriate care if needed.
