The short answer
Evaluation may include adequate lymph-node biopsy, pathology, imaging, blood tests, and selected organ-function testing. Each result should answer a specific diagnostic, risk, or treatment question.
Evaluation may include adequate lymph-node biopsy, pathology, imaging, blood tests, and selected organ-function testing.
Planning may depend on classical or nodular lymphocyte-predominant type, stage, symptoms, bulky disease, health, fertility, and goals.
A result can be diagnostic, prognostic, predictive, or useful for monitoring—and these are not identical roles.
Ask which results are confirmed and which remain pending.

The whole article, with every detail and caution.
This page is for people reading a Hodgkin lymphoma pathology report. It explains the biopsy findings, stages, risk groups, and how these results connect to treatment.
What the biopsy shows
Diagnosis starts with a lymph-node biopsy. Doctors usually want the whole node removed (excisional biopsy) or a large piece (incisional biopsy), rather than a thin needle sample. A whole node gives the pathologist a clear view of the tissue pattern.
Under the microscope, the pathologist looks for Reed-Sternberg cells. These are large, abnormal cells that can have more than one nucleus. Finding them is the hallmark of classic Hodgkin lymphoma. There are four subtypes of classic Hodgkin lymphoma: nodular sclerosing, mixed cellularity, lymphocyte-rich, and lymphocyte-depleted. A separate, less common type is called nodular lymphocyte-predominant Hodgkin lymphoma. It is treated differently: NCI lists watchful waiting and active surveillance among its options, which are not options for the classic subtypes.
Staging after diagnosis
Once the diagnosis is confirmed, imaging and blood work determine the stage. Hodgkin lymphoma uses four stages:
- Stage I: cancer in one lymph node area.
- Stage II: two or more node areas on the same side of the diaphragm, the muscle below your lungs.
- Stage III: node areas on both sides of the diaphragm, or involvement of the spleen.
- Stage IV: the cancer has reached an organ outside the lymph system, such as the liver, lungs, bone marrow, or spinal fluid.
Your report may also add the letter A or B. B means you have had one or more of these: fever with no known cause, drenching night sweats, or unexplained weight loss. A means none of those symptoms were present. Ask your team how B symptoms affect your plan.
Why risk groups matter
Doctors sort Hodgkin lymphoma into three treatment groups: early favorable, early unfavorable, and advanced. The grouping combines your stage and B symptoms. It also factors in how many node areas are involved, and whether any single mass is unusually large (called bulky disease). This grouping, not the stage number alone, guides how strong your treatment needs to be.
How results connect to treatment
Early favorable disease is treated with combination chemotherapy, with or without radiation to the areas of the body with cancer. The regimen NCI names for this group is ABVD. Early unfavorable disease may use the same chemotherapy with radiation, or add a targeted drug called brentuximab vedotin. Advanced disease is treated with combination chemotherapy, sometimes combined with the immunotherapy drug nivolumab or with brentuximab vedotin.
If Hodgkin lymphoma returns after treatment, options include immunotherapy with pembrolizumab or nivolumab, and brentuximab vedotin. Another option is high-dose chemotherapy followed by an autologous stem cell transplant. In this procedure, your own blood-forming cells are collected and stored. They are given back after high-dose treatment to help your bone marrow recover.
What's still pending
PET scans done partway through treatment can show how well the chemotherapy is working. Your team may use that result to decide whether to adjust the plan. Ask when that scan is planned and what result would change your treatment.
What to ask your team
- Do I have classic Hodgkin lymphoma or the nodular lymphocyte-predominant type?
- What stage and risk group do I fall into, and why?
- Do I have B symptoms, and how does that change the plan?
- What is bulky disease, and do I have it?
- When will a mid-treatment scan happen, and what would it change?

Common questions
Why are so many tests needed?
Blood cancers can look similar while differing in cell type, biology, pace, and treatment response.
Does one gene result determine treatment?
Usually not by itself. The team interprets it with the full diagnosis, disease status, health, and treatment goals.
What is measurable residual disease?
It is sensitive testing for disease remaining after treatment; its meaning and use vary by blood cancer and test.
Can results be reviewed elsewhere?
You can ask whether specialist hematopathology review would increase confidence or change planning.

Review details and limits
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, and this 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 then compared with the sources listed on it, looking for statements those sources do not back up. That check is not a sentence-by-sentence record and can miss errors. 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.
