Lymphoma: Symptoms, Diagnosis, and Lab Testing in Miami | QuickLab Mobile

Introduction

Lymphoma is a type of blood cancer that begins in the lymphatic system, an essential part of the body’s immune defense. It develops when certain white blood cells, called lymphocytes, grow and multiply uncontrollably, forming tumors in lymph nodes and other parts of the body.

In the United States, lymphoma is one of the most common cancers, affecting both children and adults. Because its early symptoms can be vague—such as fatigue, low-grade fevers, or painless swelling of lymph nodes—many cases aren’t diagnosed until the disease has progressed. The good news is that, with timely diagnosis and modern treatment options, many forms of lymphoma are highly treatable and even curable.

In this article, we’ll break down the types of lymphoma, the signs to watch for, how it’s diagnosed, and the crucial role that lab testing plays in both detection and ongoing care.

What Is Lymphoma?

Lymphoma is a cancer that starts in the lymphatic system, a network of vessels, lymph nodes, and organs (like the spleen and thymus) that helps protect the body from infections and disease. Its job is to transport lymph—a clear fluid rich in immune cells—throughout the body, filtering out harmful substances and fighting pathogens.

When certain white blood cells called lymphocytes undergo genetic changes, they can begin multiplying uncontrollably. Instead of helping the immune system, these abnormal lymphocytes crowd out healthy cells and form masses in the lymph nodes or other tissues.

There are two main categories of lymphoma:

• Hodgkin Lymphoma (HL): Characterized by the presence of abnormal cells called Reed–Sternberg cells. HL is less common and often responds well to treatment, especially when caught early.

• Non-Hodgkin Lymphoma (NHL): A broad category that includes dozens of subtypes, ranging from slow-growing to aggressive forms.

One of the most common aggressive NHL subtypes is Diffuse Large B-Cell Lymphoma (DLBCL), which can appear in a single lymph node region or in multiple areas throughout the body. While DLBCL progresses quickly, it is also one of the most treatable forms of lymphoma when diagnosed promptly.

Types of Lymphoma

Lymphoma is classified into many different subtypes, each with its own behavior, growth rate, and treatment approach. Understanding the type is essential for determining the best care plan.

1. Hodgkin Lymphoma (HL)

• Defining feature: Presence of Reed–Sternberg cells, large abnormal lymphocytes seen under the microscope.

• Subtypes: Nodular sclerosis, mixed cellularity, lymphocyte-rich, and lymphocyte-depleted.

• Outlook: Often responds well to a combination of chemotherapy and radiation, especially if detected early.

2. Non-Hodgkin Lymphoma (NHL)

This group includes dozens of subtypes that can be classified as either indolent (slow-growing) or aggressive (fast-growing).

Common NHL subtypes include:

• Diffuse Large B-Cell Lymphoma (DLBCL): The most common aggressive NHL, making up about 30–40% of cases in the U.S. It grows quickly but is often curable with prompt treatment.

• Follicular Lymphoma: A slower-growing (indolent) form that can transform into a more aggressive type over time.

• Mantle Cell Lymphoma: An uncommon but challenging form to treat, often diagnosed at an advanced stage.

• Burkitt Lymphoma: One of the fastest-growing human tumors, requiring intensive chemotherapy.

Each subtype’s behavior and prognosis vary, making accurate diagnosis through biopsy and specialized testing critical.

Symptoms and Early Warning Signs

Lymphoma can be difficult to detect early because its symptoms often mimic those of less serious conditions. However, persistent or unexplained changes in health should always prompt medical evaluation—especially if multiple signs occur together.

Common symptoms include:

• Painless swelling of lymph nodes in the neck, armpit, or groin. This is often the first noticeable sign.

• Unexplained fever that comes and goes without an obvious cause.

• Night sweats that may be severe enough to soak clothing and sheets.

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

• Persistent fatigue that doesn’t improve with rest.

• Itching or skin rashes without a clear reason.

• Frequent infections or slow recovery due to impaired immune function.

Some symptoms, such as chest pain, cough, or abdominal swelling, may occur if enlarged lymph nodes press on internal organs.

Because these signs can easily be mistaken for infections, stress, or other illnesses, delays in diagnosis are common. This makes awareness—both among patients and healthcare providers—an essential step toward earlier detection and improved outcomes.

Risk Factors

The exact cause of lymphoma is still not fully understood, but research has identified several factors that can increase a person’s risk. Some are beyond our control, while others relate to the environment or overall health.

Known risk factors include:

• Age: While lymphoma can develop at any age, certain types are more common in older adults.

• Gender: Some subtypes are slightly more common in men, while others occur more often in women.

• Weakened immune system: This may be due to HIV infection, organ transplantation, or long-term use of immunosuppressive drugs.

• Chronic infections: Viruses such as Epstein–Barr virus (EBV), human T-cell leukemia/lymphoma virus (HTLV-1), and hepatitis C have been linked to specific lymphoma subtypes.

• Family history: Having a close relative with lymphoma may increase the risk slightly.

• Autoimmune disorders: Conditions such as rheumatoid arthritis, lupus, and celiac disease are associated with a higher risk.

• Environmental exposure: Long-term contact with pesticides, herbicides, or industrial solvents may contribute to lymphoma development.

It’s important to note that many people with one or more risk factors never develop lymphoma, while others with no known risk factors can still be diagnosed. Regular check-ups and prompt evaluation of suspicious symptoms remain the best strategies for early detection.

How Lymphoma Is Diagnosed

Diagnosing lymphoma requires a combination of clinical evaluation, imaging studies, and laboratory analysis. Because symptoms can be vague, the process often starts with ruling out other possible causes before confirming the disease.

1. Physical Examination
A healthcare provider will check for swollen lymph nodes in the neck, armpits, or groin, as well as signs of enlargement in the spleen or liver.

2. Imaging Tests

• CT scans and PET scans help determine the size and location of affected lymph nodes and whether the disease has spread.
  
  

• MRI scans may be used in specific cases, especially if the brain or spinal cord is involved.

3. Lymph Node Biopsy – The gold standard
A biopsy involves removing part or all of a lymph node so a pathologist can examine the cells under a microscope. This confirms whether lymphoma is present and identifies the specific type and subtype.

4. Laboratory Tests
Blood work provides critical information on a patient’s overall health and disease activity:

• Complete Blood Count (CBC): Checks for anemia, low white cell counts, or low platelets.

• Lactate Dehydrogenase (LDH): Elevated levels may indicate more aggressive disease.

• Erythrocyte Sedimentation Rate (ESR) & C-reactive Protein (CRP): Markers of inflammation.

• Beta-2 Microglobulin: Can help with staging and prognosis.

For ongoing care, these tests are repeated regularly to monitor treatment response and detect early signs of recurrence.

Treatment Options

The treatment plan for lymphoma depends on its type, stage, growth rate, and the patient’s overall health. Some slow-growing lymphomas may require a “watch-and-wait” approach, while aggressive types need immediate intervention.

1. Chemotherapy
Often the backbone of lymphoma treatment, chemotherapy uses drug combinations—such as the R-CHOP regimen for diffuse large B-cell lymphoma—to kill rapidly dividing cancer cells.

2. Immunotherapy
Treatments like rituximab (a monoclonal antibody) target specific proteins on lymphoma cells, helping the immune system recognize and destroy them.

3. Radiation Therapy
High-energy beams are used to target and destroy cancer cells in specific areas. This is often combined with chemotherapy in early-stage disease.

4. Targeted Therapy
Newer medications interfere with specific pathways or proteins essential for cancer cell growth, often with fewer side effects than traditional chemotherapy.

5. Stem Cell Transplant
For relapsed or refractory cases, high-dose chemotherapy followed by a stem cell transplant can restore healthy bone marrow function.

6. Supportive Care
Managing symptoms, preventing infections, and addressing treatment side effects are essential parts of the care plan—especially for patients with other chronic conditions.

Thanks to advances in treatment, many lymphomas are now highly treatable and even curable, particularly when diagnosed early.

The Role of Lab Testing in Ongoing Care

Lab testing isn’t just important for diagnosis—it’s essential for monitoring treatment response, tracking side effects, and detecting recurrence.
Regular blood work allows healthcare providers to:

• Assess bone marrow function during chemotherapy.

• Track LDH and beta-2 microglobulin levels as indicators of disease activity.

• Monitor immune function to prevent infections.

• Detect early signs of relapse before symptoms appear.

For many patients, especially those managing other health conditions like diabetes or cardiovascular disease, routine lab monitoring can be challenging.
