# Symptoms and Phases of Non-Hodgkin Lymphoma
Non-Hodgkin lymphoma (NHL) does not always progress in clear, sequential phases like some other cancers. The course of the disease depends a lot on the type of NHL, how fast it grows and where it originated in the body. Some patients have no symptoms and the disease is discovered by chance; others have complaints even before the diagnosis is made. The following describes how NHL usually appears and how it progresses.
Early stage (stage I-II): local or limited infestation
At an early stage, lymphoma is limited to one or two groups of lymph nodes, often in the same body region (e.g. in the neck or under the arm).
**Symptoms that may occur:**
- Swollen lymph nodes (lymph nodes) that feel soft and are not painful; they can remain stable for several weeks or months
- Sometimes mild tiredness or feeling unwell
- In case of involvement of glands in the abdominal cavity: misunderstood abdominal pain or feeling full after small amounts of food
- In case of involvement of glands in the breast: possible cough or slight tightness
Many patients have little or no symptoms at this stage and discover the disease by chance (e.g. when examining for something else) or because a gland happens to feel larger.
**Meaning for daily life:**
For many, everyday life still feels almost normal, because the disease does not yet have a serious impact on energy levels or body weight. However, some notice that fatigue occurs somewhat faster than before.
**Numbers about this stage:**
The median survival for patients with early stage indolent (slow growing) NHL is ten years or more; for aggressive (rapidly growing) NHL, this is more differentiated by subtype (source: NCCN guidelines, 2024-2025). These are averages across large groups; individual outcomes can vary widely and depend on many factors, including the exact NHL type, age, and overall health.
Intermediate stage (stage III): spread to both sides of the diaphragm
At this stage, lymph nodes on both sides of the diaphragm are affected, or the disease has spread to multiple parts of the body while certain organs are not yet involved.
**Symptoms that may occur:**
- Swollen lymph nodes in multiple areas (neck, armpits, both sides of the abdomen)
- Increasing tiredness, especially during exercise
- Night sweats (sometimes so strong that patients have to change their pajamas)
- Fever that occurs without a clear infection and sometimes disappears
- Unexplained weight loss (more than 10% of body weight over a few months)
- Itching all over the body, which is sometimes very annoying
- Enlarged spleen (palpable as heaviness under the left ribs) or enlarged liver
**Meaning for daily life:**
At this stage, many patients feel noticeably less fit. Although normal activities are often still possible, exercise can lead to exhaustion sooner. Night sweats can cause insomnia. Itching can interfere with concentration or relaxation. Many patients find that they are less able to work or do fewer household chores.
**Numbers about this stage:**
For intermediate stage indolent NHL, median survival varies between 5 and 15 years depending on further risk factors; for aggressive NHL, this is much shorter without treatment but significantly better with treatment (source: various NHL prognostic models, 2024). Again: these are population figures, not individual forecasts.
Advanced stage (stage IV): spread to organs outside the lymphatic system
In stage IV, lymphoma has grown outside the lymph nodes to other organs such as bone, brain, liver, lungs, or intestines. This may be associated with more serious symptoms.
**Symptoms that may occur:**
- All signs from earlier stages, often more pronounced
- Bone pain or fracture when skeletal system is affected
- Headaches, concentration problems or neurological complaints such as the brain are involved
- Cough, shortness of breath, or chest pain when lungs are affected
- Diarrhea, abdominal pain, or blood in stool if bowels are involved
- Yellow skin or itching (pruritus) if liver is affected
- Significant weight loss and muscle weakness
- Severe anemia with dizziness and shortness of breath
- Infections that occur more frequently because the immune system is weakened
**Meaning for daily life:**
Daily life is considerably affected. Many patients feel very fatigued, can no longer work, and need help with household tasks. Hospital visits become more frequent. Some symptoms, such as pain or severe itching, can be quite burdensome. The psychological impact of advanced disease is significant.
**Numbers about this stage:**
For advanced indolent NHL, median survival (without treatment or considering natural course) is several years; with modern treatments considerably longer. For advanced aggressive NHL, median survival without treatment is months to approximately one and a half years; with treatment, especially if patients respond well, median survivals of 3 to more than 10 years can be achieved, depending on NHL type and response to therapy (source: NCCN, ESMO guidelines 2024-2025). These figures say nothing about any individual; many patients survive longer, others shorter.
Remission: partial or complete disappearance of symptoms
After treatment, symptoms can completely disappear (complete remission) or improve significantly (partial remission). This can take weeks to months after treatment starts.
**What can happen:**
- Swollen lymph nodes shrink and disappear gradually
- Night sweats stop, sleep improves
- Energy level rises gradually
- Itching disappears
- Weight can slowly increase again
- Blood values normalize step by step
**Meaning for daily life:**
This is a major turning point. Many patients feel much better and can do more. Work can resume, social activities recover. Physically they feel considerably stronger. Psychologically, the relief is usually enormous. However, the fear of the disease returning may remain.
**What to watch for:**
During remission, regular medical check-ups remain necessary (blood tests, sometimes imaging) to detect early if the disease returns. This provides coverage if the lymphoma begins to expand again before symptoms appear.
Relapse (recurrence) or progression: growth of the lymphoma after remission or during treatment
Sometimes the lymphoma grows back after a period of remission, or continues to grow despite treatment. This is known as relapse or progressive disease.
**Symptoms that can reappear:**
- Return of swollen lymph nodes (sometimes in the same location, sometimes in new locations)
- Fatigue that increases again
- Fever, night sweats, or weight loss
- Other symptoms that also occurred at initial diagnosis
**Meaning for daily life:**
The impact depends on how quickly the disease returns and to what extent. With slow recurrence, many activities can still continue. With rapid progression, patients feel worse much faster and require new or more intensive treatment.
**Statistics on relapse:**
This varies greatly by NHL type and by individual. For indolent NHL: even after initial treatment, recurrence is possible, sometimes after years. For aggressive NHL, it depends on the initial response to treatment; good responders have better prospects (source: NCCN, 2024). No general figure can be given here without specifying NHL type.
Treatment-resistant or refractory disease: no or insufficient response to treatment
In some patients, the lymphoma does not respond well to standard treatment, or the response is only brief. This is called refractory or treatment-resistant disease.
**What can occur:**
- Swollen lymph nodes do not shrink, or shrink only very slightly
- Symptoms such as fatigue, fever, or weight loss persist despite treatment
- Blood values do not normalize
**Meaning for daily life:**
This is a difficult phase, because the disease continues and patients feel continuously ill. New treatment options are being investigated, which may mean that patients want to participate in clinical trials or switch to more advanced therapies (for example CAR-T cell therapy). Daily life is continuously affected by symptoms.
**What to watch for:**
Contact with the treating physician is frequent in refractory disease, because the doctor regularly evaluates whether the current plan is appropriate and which alternatives are available.

When to contact your doctor
Regardless of which phase you are in, contact your doctor or hospital when:
- You suddenly become much weaker or can no longer do your daily activities
- You develop a fever (38°C or higher) that does not go away, especially combined with chills
- You have severe breathing difficulties or chest pain
- You have severe abdominal pain, especially if accompanied by vomiting
- You see blood in your stool, urine or cough, or vomit blood
- You notice suddenly new swollen lymph nodes that grow quickly
- You have severe signs of infection (high fever, confused thoughts, severe weakness)
- Your symptoms change greatly or feel different from before
These warning signals may indicate complications or changes in your disease for which your treating physician needs to see you.
