Waldenström macroglobulinemia is a rare type of slow-growing blood cancer. It starts in B-lymphocytes (a type of white blood cell) inside the bone marrow. These B-cells become abnormal and behave like a mix between a lymphoma cell and a plasma cell. They make large amounts of a single antibody called IgM (immunoglobulin M). Because IgM is a big, heavy protein, too much of it can make the blood thick and sticky (this is called hyperviscosity). Thick blood flows more slowly and may cause headaches, nosebleeds, vision problems, or confusion. The cancer cells can also crowd out healthy marrow, causing anemia (tiredness, shortness of breath), low platelets (easy bruising or bleeding), and low white cells (more infections).
Waldenström macroglobulinemia (WM) is a cancer of white blood cells called B cells. In WM, these B cells partly turn into plasma-like cells and build up in the bone marrow. These abnormal cells make a single type of antibody called IgM in very large amounts. Too many of these cells in the marrow can crowd out normal blood-forming cells and cause anemia (low red cells), low platelets, or low white cells. Too much IgM can also make the blood thick (this is called hyperviscosity), which can lead to problems like blurred vision, headaches, nosebleeds, and confusion. Doctors classify WM as a lymphoplasmacytic lymphoma that always has a monoclonal IgM protein in the blood. That is the key idea: lymphoplasmacytic lymphoma + IgM spike = WM. PMCWaldenstrom’s FoundationScienceDirect
At the DNA level, most people with WM have a change (mutation) in a signaling gene called MYD88 (most often L265P). A smaller group also has mutations in CXCR4. These mutations help the cancer cells stay alive and divide. Testing for these mutations helps doctors confirm the diagnosis and sometimes guides treatment choices. PMCAACR Journals
Types
There is no single “official” list of types like you might see for some other cancers, but doctors commonly describe WM in the following practical subgroups to guide monitoring and care:
-
Asymptomatic (smoldering) WM
You have the typical WM lab pattern (bone-marrow LPL cells plus an IgM spike), but no symptoms and no organ damage. Many people can be safely observed without immediate treatment. PubMed -
Symptomatic (active) WM
WM is causing anemia, thick blood (hyperviscosity), enlarged lymph nodes or spleen, nerve damage (neuropathy), kidney, heart, or other organ problems, or systemic symptoms (fever, night sweats, weight loss). Treatment is recommended. PubMed -
IgM-related disorders linked to WM cells
Sometimes the IgM or the LPL cells cause special problems:
• Hyperviscosity syndrome (thick blood causing neurologic and eye symptoms)
• Cold agglutinin disease (IgM sticks to red cells in the cold and causes hemolysis)
• Cryoglobulinemia (proteins that precipitate in the cold, leading to skin, nerve, or kidney issues)
• Anti-MAG neuropathy (IgM damages myelin on peripheral nerves, causing numbness/tingling and imbalance)
These problems are common reasons people need therapy. NCBIWaldenstrom’s Foundation -
Central nervous system (CNS) involvement — Bing–Neel syndrome
Rarely, WM cells enter the brain or spinal cord. People can have headaches, cognitive changes, balance issues, or vision problems. Diagnosis uses MRI and CSF testing. Treatment differs from standard WM therapy. PMCHaematologica -
Genetic profile–based groups
• MYD88-mutated / CXCR4-wild type (most common)
• MYD88-mutated / CXCR4-mutated (about a third)
• MYD88-wild type (uncommon; may behave differently and is important diagnostically) PMC+1
Causes and contributing risk factors
Important context: For most people, the exact cause of WM is unknown. Researchers have identified risk factors and contributors, but having a risk factor does not mean you will get WM. Below are factors linked to higher chances of WM or closely related conditions:
-
Somatic MYD88 L265P mutation – a common driver change that helps B-cells survive. It is acquired in the tumor cells; you are not born with it. PMC
-
CXCR4 mutations – occur in a sizeable minority; can affect how cells respond to signals and may influence symptoms. PMC
-
Age – WM is much more common in older adults (average diagnosis ~70 years). LLS
-
Male sex – men are affected more often than women. American Cancer Society
-
Race/ancestry – higher rates in people of Northern European ancestry; lower in some other groups. PMC
-
Family history – having close relatives with WM or other B-cell cancers raises risk modestly. PMC
-
IgM MGUS (a precursor condition) – some people with IgM monoclonal gammopathy progress to WM over time. Haematologica
-
Chronic immune stimulation – long-standing immune activation has been linked to LPL/WM in epidemiologic studies. Oxford Academic
-
Certain autoimmune diseases – some data suggest associations (for example, Sjögren’s, thyroiditis), but these do not prove causation. Oxford Academic
-
Hepatitis C virus (HCV) – evidence is mixed; some studies suggest an association, others do not. If present, HCV can also cause cryoglobulinemia that overlaps with WM issues. PMC+1Waldenstrom’s
-
HIV or immune deficiency – immune dysregulation may contribute; overall risk is still low at the individual level. American Cancer Society
-
Occupational exposures: pesticides – reported in pooled studies of lymphomas including LPL/WM. Oxford Academic
-
Occupational exposures: organic solvents – e.g., benzene-like solvents; signals seen in case-control work. ResearchGate
-
Wood dust and farming – associations noted in epidemiologic projects of LPL/WM. Oxford Academic
-
Possible genetic susceptibility regions – e.g., specific chromosome loci and familial clustering suggest inherited susceptibility, even though the tumor mutations are acquired. PMC
-
Epigenetic changes with aging – aging B-cells accumulate changes that may favor clonal growth (conceptual contributor across many lymphomas). PMC
-
Prior IgM-related neuropathy – in some, prolonged IgM activity (anti-MAG) reflects the same clone that later meets criteria for WM. ScienceDirect
-
Long-standing infections causing cryoglobulinemia – can coexist with or unmask IgM clones that meet WM criteria. PMC
-
Male hormonal milieu / lifestyle correlates – male predominance exists, but specific hormone or lifestyle causes remain unproven; listed here to explain the observed pattern. PMC
-
Random chance – as with many cancers, chance errors in dividing cells can accumulate over life; many people have no identifiable risk factor. PMC
Common signs and symptoms
Not everyone has all symptoms. Some people feel well and are diagnosed from routine blood tests. When symptoms occur, they often relate to anemia, thick blood (hyperviscosity), nerve problems, bleeding, or organ enlargement:
-
Tiredness and weakness – usually from anemia when the marrow is crowded by WM cells. American Cancer Society
-
Shortness of breath with effort – another effect of anemia and thick blood. American Cancer Society
-
Unintentional weight loss – a general “B symptom” of lymphomas. American Cancer Society
-
Fever and night sweats – systemic inflammation from lymphoma activity. American Cancer Society
-
Easy bruising or nosebleeds – from low platelets or interference of IgM with clotting. American Cancer Society
-
Headache, dizziness, ringing in ears, confusion – classic hyperviscosity symptoms due to sluggish blood flow. Emergency treatment (plasmapheresis) may be needed if severe. NCBI
-
Blurred or double vision – hyperviscosity damages tiny retinal vessels; eye exam may show “sausage-link” veins or retinal hemorrhages. NCBI
-
Numbness, tingling, imbalance – peripheral neuropathy, often related to IgM antibodies attacking myelin (e.g., anti-MAG). Waldenstrom’s Foundation
-
Cold-triggered color change or pain in fingers/toes – cryoglobulins or cold agglutinins can impair circulation in the cold. PMC
-
Enlarged lymph nodes – due to lymphoma tissue outside the marrow. PMC
-
Fullness under left ribs or early satiety – from enlarged spleen; liver can also enlarge. PMC
-
Recurrent infections – abnormal antibodies don’t protect well, and normal antibodies may be low. PMC
-
Skin changes (purpura, livedo, ulcers) – from cryoglobulinemia, hyperviscosity, or low platelets. PMC
-
Bone pain is uncommon – lytic bone lesions typical of myeloma are usually absent in WM, which helps tell them apart. LLS
-
Neurologic changes from CNS involvement (rare) – in Bing–Neel syndrome: cognitive changes, gait issues, cranial nerve symptoms. PMC
Diagnostic tests
Doctors combine your story, exam, labs, marrow testing, and imaging to make the diagnosis. The essentials are: finding lymphoplasmacytic lymphoma in the bone marrow and confirming a monoclonal IgM in the blood; MYD88 testing is strongly recommended. Below are 20 tests explained in simple words. Waldenstrom’s FoundationLLS
A) Physical examination
-
General exam with vital signs and performance status
Checks fever, weight loss, heart rate, blood pressure, and how active you can be. This helps stage urgency and safety for treatment decisions. PMC -
Lymph-node, liver, and spleen exam
Doctors feel the neck, armpits, groin, abdomen for enlarged nodes or organs, which suggest disease beyond the marrow. PMC -
Bedside eye (funduscopic) exam
Using an ophthalmoscope to look for “sausage-link” veins, hemorrhages, or swelling of the optic disc—signs of hyperviscosity that need urgent attention. NCBI
B) Manual (bedside) tests
-
Snellen visual-acuity chart
A quick way to document blurry vision from hyperviscosity or retinal changes and to monitor improvement after treatment. NCBI -
Orthostatic (lying-to-standing) blood pressure
Screens for dizziness related to thick blood or anemia and helps detect volume issues before therapies like plasmapheresis. NCBI -
10-g monofilament and 128-Hz tuning-fork vibration tests
Simple bedside checks for large-fiber neuropathy in the feet and hands from IgM-related nerve damage. Waldenstrom’s Foundation
C) Laboratory & pathological tests
-
Complete blood count (CBC) with differential + peripheral smear
Looks for anemia, low platelets, or abnormal lymphoplasmacytic cells; the smear helps spot rouleaux and other red-cell changes. PMC -
Serum protein electrophoresis (SPEP) with immunofixation (IFE)
Identifies and confirms a monoclonal IgM (“M-protein”). This is a core test for WM. PMC -
Quantitative immunoglobulins (IgM, IgG, IgA)
Measures exact IgM level and checks if protective IgG/IgA are low, which can cause infections. PMC -
Serum viscosity (SV)
Measures how thick the blood is; guides the need for urgent plasmapheresis when symptoms of hyperviscosity appear. Waldenstrom’s Foundation -
Serum free light chains ± 24-hour urine IFE/UPEP
Looks for extra light chains that may contribute to kidney or amyloid issues and helps in the differential with myeloma. PMC -
β2-microglobulin and LDH
“Tumor-burden” and cell-turnover markers that aid risk stratification and prognosis. Waldenstrom’s Foundation -
Bone marrow aspirate and core biopsy with morphology/IHC
This is diagnostic: shows lymphoplasmacytic lymphoma in the marrow. Pathologists use stains for B-cell markers (CD19, CD20, surface IgM, light-chain restriction). PMC -
Flow cytometry (marrow and/or blood)
Confirms the immunophenotype typical of WM and helps distinguish WM from look-alikes (e.g., marginal zone lymphoma, CLL, IgM myeloma). PMC -
MYD88 L265P mutation testing (AS-PCR or ddPCR)
Strongly recommended in guidelines; positive in ~90% of WM and supports the diagnosis. LLSPMC -
CXCR4 mutation testing
Present in ~30%; may correlate with certain symptoms and sometimes influences drug responses. PMC
D) Electrodiagnostic studies
-
Nerve conduction studies (NCS)
Detect demyelinating neuropathy typical of anti-MAG–related nerve damage (slowed conduction, prolonged distal latencies). PMC+1 -
Electromyography (EMG)
Complements NCS to characterize neuropathy pattern and to rule out other causes of weakness. PMC
E) Imaging tests
-
CT scan of chest/abdomen/pelvis
Looks for lymph-node enlargement, liver or spleen enlargement, and guides staging and treatment planning. PMC -
MRI of brain/spine (if neurological “red flags”)
Essential when Bing–Neel syndrome is suspected; often paired with CSF analysis to prove CNS involvement. PMC

Frequently Asked Questions (FAQs)
-
Is WM curable?
WM is usually not considered curable, but it is often very treatable. Many people live for years with good quality of life using periodic treatments. -
Do all patients need immediate treatment?
No. If you have no symptoms and labs are stable, a watch-and-wait approach is safe. Start treatment when symptoms or complications appear. -
What triggers urgent treatment?
Hyperviscosity symptoms, severe anemia, repeated infections, kidney issues from IgM, significant neuropathy, cryoglobulinemia, or organ enlargement that causes problems. -
Why does rituximab sometimes raise IgM at first?
It can cause an “IgM flare”—a temporary increase. Doctors may use plasmapheresis around treatment to prevent complications if your baseline IgM is very high. -
What are BTK inhibitors and why are they important?
They are pills that block Bruton’s tyrosine kinase, a key survival signal for WM cells. They have changed WM care because many patients respond well and can take them long-term. -
Which BTK inhibitor is “best”?
Your doctor chooses based on your heart health, other illnesses, drug interactions, and local approvals. Zanubrutinib is often favored for its balance of efficacy and safety; others (ibrutinib, acalabrutinib) are also used based on circumstances. -
Will I lose my hair?
Many WM regimens cause less hair loss than classic chemotherapy. Hair loss risk depends on the drugs used. -
Can WM cause nerve problems?
Yes. IgM can attack nerves (anti-MAG neuropathy), and some medicines can worsen neuropathy. Your team will tailor drugs and schedules to protect nerves. -
How often will I need blood tests?
During watchful waiting, typically every 3–6 months. During treatment, labs are more frequent (often before each cycle or monthly with BTK inhibitors). -
Can I travel?
Yes—plan ahead. Carry medication lists, get travel insurance, stay hydrated, and move legs on long trips to reduce clot risk. -
Can diet or supplements treat WM?
No. They support overall health but do not replace medical treatment. Always check for interactions. -
Is stem cell transplant common in WM?
It’s selective—used for fit patients with relapsed disease at specialized centers. It is not routine for everyone. -
Will treatment affect my heart?
Some medicines (e.g., ibrutinib) can affect heart rhythm or blood pressure. Your team will monitor and may choose alternatives if you have heart disease. -
What if I’m bleeding or bruising easily?
Tell your team promptly. Platelets may be low or a drug may raise bleeding risk. You may need dose changes or added precautions. -
Are clinical trials worth considering?
Yes. Trials offer access to new therapies and expert care. Ask your oncologist about options at academic centers.
