The short answer
A burkitt lymphoma evaluation may include urgent biopsy and pathology, imaging, blood and marrow tests, and CNS assessment when indicated. The goal is to confirm the exact diagnosis and gather information that changes care.
Evaluation may include urgent biopsy and pathology, imaging, blood and marrow tests, and CNS assessment when indicated.
Not every person needs every possible test.
Planning may depend on age, stage, tumor burden, organ function, CNS or marrow involvement, and treatment fitness.

The full explanation.
What brings it to light
Burkitt lymphoma grows and spreads very quickly, often over just days to weeks. That sets it apart from many other lymphomas. It occurs most often in children and young adults. It can show up as swelling in the jaw or facial bones. It can also appear as a mass in the abdomen, affecting the bowel, kidneys, or ovaries. Because it grows so fast, symptoms often prompt urgent evaluation rather than a slow workup.
The tests that confirm it
A lymph node or tissue biopsy is required to confirm the diagnosis. This can be an excisional, incisional, or core needle biopsy, depending on where the mass is. Once tissue is available, several lab tests examine it in detail. Immunohistochemistry looks at specific proteins on the cells. Cytogenetic analysis checks the chromosomes. FISH testing looks for specific gene changes. Because Burkitt lymphoma can spread to the brain and spinal cord, doctors also check the fluid around the spinal cord.
Why this diagnosis moves faster than most
Burkitt lymphoma's speed changes how the whole process works. Tests are often ordered and read urgently, sometimes within a day or two. Slower cancers commonly take a week or more instead. If you or your child has this diagnosis, expect appointments and next steps to be scheduled quickly. That pace reflects how the disease behaves, not a sign that something has gone wrong.
Why tumor lysis syndrome is a concern from day one
Burkitt lymphoma cells multiply so fast that treatment itself can cause many cells to break down all at once. This releases their contents into the blood. This is called tumor lysis syndrome, and it can affect the kidneys and heart if not managed closely. Your team will likely start IV fluids and monitor blood chemistry closely, from the very first treatment. This problem can develop quickly, even before you feel unwell.
What to ask your team
- What type of Burkitt lymphoma is this: endemic, sporadic, or immunodeficiency-related?
- Has the spinal fluid been checked for lymphoma cells?
- What is being done to prevent tumor lysis syndrome?
- How quickly does treatment need to start, based on how this is growing?
- What symptoms during treatment need an immediate call, not a wait-and-see approach?
When to get help sooner
While you are being worked up or starting treatment, some symptoms should not wait for the next appointment.
- Call 911 or go to an emergency department if you have trouble breathing, swelling of the face or neck, chest pain, a seizure, sudden confusion, or you pass out.
- Call your treatment team the moment a temperature of 100.4°F (38°C) or higher shows up once chemotherapy has started, or with shaking chills. CDC treats a fever during chemotherapy as a medical emergency, not something to sit on (CDC). Call even at night or on a weekend, go to an emergency department if you cannot reach anyone quickly, and do not take anything to bring the temperature down first.
- Call your care team the same day if you pass much less urine than usual, get muscle cramps or a racing heart, or your belly pain and vomiting get worse. These can be signs of tumor lysis syndrome.
- Call your care team within a day or two if a lump or swelling is clearly bigger, or you have new numbness, weakness, headaches, or trouble seeing.

Common questions
What makes Burkitt lymphoma different from other lymphomas?
It grows and spreads very quickly, often over just days to weeks. It occurs most often in children and young adults. It can show up as swelling in the jaw or facial bones, or as a mass in the abdomen affecting the bowel, kidneys or ovaries. Because it grows so fast, symptoms often prompt urgent evaluation rather than a slow workup.
Which tests confirm the diagnosis?
A lymph node or tissue biopsy is required. It may be excisional, incisional or core needle, depending on where the mass is. Once tissue is available, immunohistochemistry looks at specific proteins on the cells, cytogenetic analysis checks the chromosomes, and FISH testing looks for specific gene changes.

What is tumor lysis syndrome, and why does it come up on day one?
Burkitt lymphoma cells multiply so fast that treatment itself can cause many cells to break down at once, releasing their contents into the blood. That is tumor lysis syndrome, and it can affect the kidneys and heart if it is not managed closely. Your team will likely start IV fluids and monitor blood chemistry from the very first treatment, because it can develop quickly even before you feel unwell.

How this page was created
Cancer Explained does not originate medical claims. Every page restates guidance already published by the National Cancer Institute, the CDC, the USPSTF and the FDA, in plain language, with the source cited so you can check the original yourself. AI does the translating and organizing; automated checks test claims, citations, clarity and safety before anything publishes. We do not employ clinicians and do not intend to — our work is translation and navigation, not clinical judgment. Nothing here is personal medical advice, and no page can account for your particular situation.
Editorial status — Source checked. This page was written with AI assistance and checked line by line against the sources listed on it. That confirms the sources support what the page says. It is not a medical review, and it does not confirm the page is complete or right for your situation.
General education — varies by person. Answers genuinely differ between people. This page explains what commonly varies and points you to your care team for your situation.
Human medical review: not completed. Pages here are not signed off by a clinician before they publish. That is not an oversight we are quietly working around: we restate published guidance and cite it, so the authority belongs to the source rather than to us, and every page names where its claims come from — you can verify us instead of trusting us. Where a volunteer clinician has reviewed a page, their name and credentials appear on it; where no name appears, no clinician has checked it. We are glad to have reviewers and are recruiting them, and we do not hold pages back waiting for one. Use this site to understand your situation and to ask better questions of the people treating you.
