How do I know if I have Non-Hodgkin's lymphoma?

Non-Hodgkin's lymphoma is a cancer that originates in the lymphatic system, and it is primarily identified through persistent, unexplained swelling of lymph nodes and systemic "B-symptoms." Because these signs can mimic common infections, a formal diagnosis of Non-Hodgkin's lymphoma requires clinical evaluation, physical examination, and diagnostic imaging or biopsy rather than self-diagnosis.

What are the early warning signs of Non-Hodgkin's lymphoma?

The most common clinical presentation of Non-Hodgkin's lymphoma involves painless swelling of the lymph nodes in the neck, underarms, or groin. Patients often report systemic symptoms known as "B-symptoms," which are important indicators for physicians to investigate further.

• Persistent, painless lymphadenopathy (swollen nodes).


• Unexplained fever (often without an obvious infection).


• Drenching night sweats.


• Unintentional weight loss of more than 10% of body weight over six months.


• Persistent fatigue or localized pain in the chest or abdomen.

When should I consult a physician about Non-Hodgkin's lymphoma?

You should schedule an appointment if you notice lymph node swelling that persists for more than two to four weeks without a clear cause like a recent infection. When speaking to your doctor, be specific about the duration of your symptoms and any systemic changes. If your concerns are dismissed, advocate for yourself by requesting a physical examination and basic blood work, such as a Complete Blood Count (CBC) and Lactate Dehydrogenase (LDH) levels, which can help screen for markers associated with Non-Hodgkin's lymphoma.

How is a diagnosis of Non-Hodgkin's lymphoma confirmed?

There is no single self-test for this condition. If a physician suspects Non-Hodgkin's lymphoma, they will typically order imaging studies like a PET/CT scan to assess lymph node involvement. The gold standard for confirming a diagnosis of Non-Hodgkin's lymphoma is a lymph node biopsy, where a pathologist examines the tissue under a microscope to identify specific malignant cells.

Next steps

• Schedule a physical exam with your primary care provider to discuss persistent lymph node swelling.


• Keep a symptom diary to track the frequency of night sweats, fevers, and weight loss.


• Connect with the 96 members in our DiseaseMaps.org community who are navigating life with Non-Hodgkin's lymphoma to share experiences.


• Request a referral to an oncologist or hematologist if initial tests show abnormalities.
