Understanding Medical Malpractice

If a medical professional’s negligence led to the misdiagnosis of Non-Hodgkin Lymphoma, it may be considered medical malpractice. At The Baer Law Firm, we help patients and their families pursue justice when diagnostic errors result in harm. If you or a loved one has been affected, you may be entitled to compensation for medical expenses, lost wages, and pain and suffering.
Understanding Non-Hodgkin Lymphoma and Its Diagnosis
Non-Hodgkin Lymphoma (NHL) is a type of cancer originating in the lymphatic system, which is responsible for fighting infections and maintaining fluid balance in the body. Unlike Hodgkin Lymphoma, NHL consists of multiple subtypes that can vary in aggressiveness and progression. NHL often begins in the lymph nodes but can spread to other organs, including the bone marrow, spleen, and digestive tract. Early detection of NHL is critical, as timely treatment significantly improves outcomes and can prevent the disease from advancing to later, more difficult-to-treat stages.
Diagnosing NHL requires a comprehensive medical evaluation, as its symptoms—such as swollen lymph nodes, fatigue, night sweats, fever, and unexplained weight loss—can be mistaken for less serious conditions like infections or autoimmune disorders. Physicians use blood tests, imaging scans (CT, MRI, or PET), and lymph node biopsies to confirm a diagnosis. The biopsy allows pathologists to analyze cancerous cells and determine the specific subtype of NHL. When doctors fail to recognize symptoms, dismiss concerns, or misinterpret test results, the consequences can be severe, leading to delayed treatment, unnecessary procedures, and a worsened prognosis.
Types of Non-Hodgkin Lymphoma
Non-Hodgkin Lymphoma (NHL) is classified into different subtypes based on how the cancer cells grow and spread. The two primary categories are aggressive (fast-growing) NHL and indolent (slow-growing) NHL. Accurate diagnosis is critical, as the treatment plan and prognosis depend on the specific type of NHL a patient has. When the type of NHL is misdiagnosed, patients may receive unnecessary treatments or experience dangerous delays in proper care.
Aggressive (Fast-Growing) Non-Hodgkin Lymphoma
These subtypes spread quickly and require immediate treatment:
- Diffuse Large B-Cell Lymphoma (DLBCL) – The most common aggressive NHL, accounting for nearly 30% of cases. Without prompt treatment, it can rapidly spread to organs beyond the lymphatic system.
- Burkitt Lymphoma – A highly aggressive subtype that progresses rapidly but responds well to intensive chemotherapy when diagnosed early.
- Mantle Cell Lymphoma (MCL) – A rare but fast-growing form of NHL that is often diagnosed at an advanced stage, requiring aggressive treatment.
Indolent (Slow-Growing) Non-Hodgkin Lymphoma
These subtypes progress slowly and may not cause symptoms for years:
- Follicular Lymphoma – The most common indolent NHL, often discovered incidentally during routine medical exams. Misdiagnosis can lead to delays in treatment if symptoms eventually worsen.
- Marginal Zone Lymphoma (MZL) – Often linked to chronic infections and autoimmune disorders, this subtype may be mistaken for benign conditions.
- Small Lymphocytic Lymphoma (SLL) – Closely related to chronic lymphocytic leukemia (CLL), this slow-growing lymphoma primarily affects the lymph nodes and bone marrow.

How Misdiagnosis of Non-Hodgkin Lymphoma Occurs
As discussed, Non-Hodgkin Lymphoma can be challenging to diagnose because its symptoms often resemble less severe conditions. However, patients can suffer severe consequences when doctors fail to recognize warning signs, order appropriate tests, or correctly interpret results. A misdiagnosis or delayed diagnosis of NHL can lead to unnecessary treatments, disease progression, and reduced survival rates. Below are some of the most common reasons why NHL is misdiagnosed.
Failure to Recognize Symptoms
NHL symptoms can be vague, making it easy for doctors to mistake them for common infections, autoimmune disorders, or other non-cancerous conditions. Swollen lymph nodes, fever, night sweats, fatigue, and unexplained weight loss are hallmark symptoms of NHL, but they can also occur in illnesses such as viral infections, mononucleosis, or rheumatoid arthritis.
In some cases, physicians may dismiss these symptoms as temporary, failing to conduct further testing. This is especially problematic for indolent (slow-growing) NHL, where symptoms may not be severe at first, leading to delayed detection and treatment. When doctors do not take persistent or worsening symptoms seriously, patients may not receive a timely referral to an oncologist or hematologist for further evaluation.
Misinterpretation of Diagnostic Tests
Accurate diagnosis of NHL relies on imaging scans, blood tests, and biopsies, but errors in interpreting these results can lead to misdiagnosis or missed diagnoses. Common diagnostic mistakes include:
- False negatives on imaging tests – A CT or MRI scan may fail to detect lymphoma in its early stages, leading doctors to rule out cancer prematurely.
- Biopsy misinterpretation – A lymph node biopsy is essential for confirming NHL, but if a pathologist misidentifies the type of cells present, it can lead to an incorrect or incomplete diagnosis.
- Incomplete bloodwork analysis – Certain blood abnormalities, such as elevated lactate dehydrogenase (LDH) levels, can be markers for NHL, but if doctors do not order the right blood tests or misinterpret the results, a crucial warning sign may be overlooked.
Errors in diagnostic testing delay appropriate treatment and can result in patients receiving unnecessary or ineffective therapies for a condition they do not have.
Delays in Referral to Specialists
When primary care physicians suspect NHL, they should promptly refer patients to a hematologist or oncologist for further testing. However, in many cases, referrals are delayed due to a failure to recognize the urgency of symptoms or an incorrect assumption that the condition is benign.
Delays in specialist referrals can allow aggressive NHL subtypes, such as Diffuse Large B-Cell Lymphoma (DLBCL), to spread rapidly, reducing the chances of a successful outcome. Even in cases of slow-growing NHL, a late diagnosis can mean the difference between early intervention and a more advanced, harder-to-treat disease.
Consequences of Misdiagnosis
A delayed or incorrect NHL diagnosis can have devastating effects on a patient’s health, including:
- Progression to advanced-stage lymphoma, which may require more aggressive and difficult treatments.
- Unnecessary treatments, such as antibiotics, corticosteroids, or medications for autoimmune diseases, which do not address the real underlying condition.
- Emotional and financial burdens, as patients may undergo multiple rounds of ineffective treatments before receiving the correct diagnosis.
The consequences of misdiagnosis go beyond physical harm – they affect a patient’s quality of life, mental well-being, and financial stability. When a healthcare provider’s negligence leads to a misdiagnosis, the patient may have legal grounds to pursue a medical malpractice lawsuit to seek compensation for their suffering.
Medical Malpractice and Misdiagnosis Claims
When a doctor fails to properly diagnose Non-Hodgkin Lymphoma (NHL), the consequences can be life-altering. Patients rely on their healthcare providers to follow the accepted medical standard of care, which includes recognizing symptoms, ordering appropriate tests, and accurately interpreting results. If a physician neglects these responsibilities and a patient suffers harm as a result, it may constitute medical malpractice.
A misdiagnosis or delayed diagnosis of NHL can deprive a patient of timely treatment, increase the severity of the disease, and even reduce their chances of survival. Proving a medical malpractice claim requires demonstrating that the doctor’s negligence directly led to harm.
What Constitutes Medical Malpractice in a Misdiagnosis Case?

- Failing to recognize symptoms that should have raised concern.
- Not ordering necessary diagnostic tests such as biopsies or imaging scans.
- Misinterpreting test results leading to an incorrect or delayed diagnosis.
- Delaying referral to a specialist, which could have expedited proper treatment.
If a doctor’s failure to diagnose NHL results in disease progression, unnecessary treatments, or loss of treatment opportunities, the affected patient may have grounds for a medical malpractice claim.
Elements of a Medical Malpractice Lawsuit
To succeed in a medical malpractice claim for the misdiagnosis of NHL, a patient must prove the following:
- Doctor-Patient Relationship – The physician had a duty to provide care because the patient sought treatment.
- Breach of Duty – The doctor failed to meet the medical standard of care, meaning they did not act as a reasonably competent physician would in the same situation.
- Causation – The misdiagnosis directly led to harm, such as disease progression, delayed treatment, or unnecessary medical interventions.
- Damages – The patient suffered physical, emotional, or financial harm due to the delayed or incorrect diagnosis.
Proving a medical malpractice case requires strong evidence, including medical records, expert testimony, and documentation of harm suffered by the patient. Due to the complexity of these claims, working with an experienced medical malpractice attorney is essential to building a strong case.
