Lymphoma A Cancer in the Lymph Glands

By Medical Expert Team

Apr 24 , 2023 | 4 min read

Lymphoma is a type of lymphatic cancer that affects the lymph glands, which are part of the lymphatic system essential for immune defense. This condition impacts lymphocytes, a type of white blood cell, thereby compromising the body’s ability to fight infections. Understanding what is lymphoma cancer, its types, causes, symptoms, and modern treatments is vital for timely diagnosis and effective management. In 2025, advancements in immunotherapy and targeted biological therapies have significantly transformed the prognosis for many patients.

What is Lymphoma?

Lymphoma is a cancer originating in the lymphatic system, a network of vessels, nodes, and organs that transport lymph fluid and white blood cells throughout the body. This cancer primarily targets lymphocytes, disrupting their normal function. When these cells mutate, they divide uncontrollably and collect in lymph nodes, the spleen, or the bone marrow, eventually forming tumors that hinder the immune system.

Types of Lymphoma

Lymphomas are categorized into two main types, distinguished primarily by the presence or absence of specific cell markers under a microscope:

1. Hodgkin’s Lymphoma (HL)

Overview: Hodgkin’s Lymphoma is a rare form of lymphoma characterized by the presence of Reed-Sternberg cells (large, multi-nucleated cells that often look like "owl eyes" under a microscope). It predominantly affects young adults (ages 15-40) and older adults (over 55). It is highly treatable with modern therapies, offering excellent cure rates.
Subtypes: Classical Hodgkin Lymphoma (which accounts for 95% of cases) and Nodular Lymphocyte-Predominant Hodgkin Lymphoma.

2. Non-Hodgkin’s Lymphoma (NHL)

Overview: Non-Hodgkin’s Lymphoma is a diverse group of lymphomas that vary in severity and prognosis. It is significantly more common than Hodgkin’s Lymphoma. The incidence of NHL increases with age, typically affecting adults over 60.
Common Subtypes: Diffuse Large B-cell Lymphoma (DLBCL) – the most common aggressive type; and Follicular Lymphoma – a common slow-growing (indolent) type.

What Causes Lymphoma?

The exact cause of lymphoma remains unclear, though it is linked to genetic mutations in lymphocytes. Several risk factors have been identified:

Exposure to Chemicals: Prolonged exposure to hazardous substances like pesticides, herbicides, and benzene can elevate risks.
Viral Infections: Viruses such as HIV, Hepatitis C, and Epstein-Barr virus are linked to higher lymphatic cancer rates.
Autoimmune Disorders: Conditions like lupus or rheumatoid arthritis increase susceptibility.
Family History: A first-degree relative with the disease slightly increases personal risk.

Signs and Symptoms of Lymphoma

Common symptoms include:

Unexplained weight loss (10% or more of body weight over six months).
Persistent fever (often above 100.3°F or 38°C) without an underlying infection.
Enlarged lymph nodes, usually painless, in the neck, armpits, or groin.
Drenching night sweats that soak pajamas and bedding.
Chronic, extreme fatigue.
Persistent itching (pruritus) without a visible rash.

Understanding "B Symptoms"

In clinical oncology, the trio of fever, drenching night sweats, and significant weight loss are known as "B Symptoms." Their presence is a critical factor that helps doctors determine the intensity of required treatment.

Understanding the 4 Stages of Lymphoma

Staging describes how far the lymphatic cancer has spread. Doctors use the Ann Arbor staging system:

Stage	Extent of Spread	5-Year Survival Rate (Approx.)
Stage I	Cancer is in one lymph node region or one organ outside the lymph system.	90–95%
Stage II	Cancer is in two or more lymph node regions on the same side of the diaphragm.	90%
Stage III	Cancer is in lymph node regions on both sides of the diaphragm.	80–85%
Stage IV	Cancer has spread widely to organs (liver, lungs, or bone marrow).	63–82%

Diagnosis of Lymphoma

Accurate diagnosis is critical because treatment varies significantly between subtypes.

Physical Examination: Initial assessment of lymph node enlargement.
Imaging Tests: PET-CT scans and MRI scans help identify affected areas.
Biopsy: An excisional biopsy (removing the entire lymph node) is the gold standard.
Bone Marrow Aspiration: Determines disease spread to the bone marrow.

Treatment Options for Lymphoma

Chemotherapy: Uses drugs to destroy cancer cells. At Nanavati Max Hospital, we offer personalized chemotherapy protocols tailored to the patient’s specific subtype.
Radiation Therapy: Targets cancer cells using high-energy X-rays, often used for localized disease.
Immunotherapy and Targeted Therapy: Uses the body’s immune system to fight cancer. Monoclonal antibodies (like Rituximab) and CAR T-cell therapy have revolutionized treatment for aggressive cases.
Stem Cell Transplant: Recommended for relapsed cases to replace diseased bone marrow.

Conclusion

Lymphoma, though serious, is increasingly treatable as of 2025. Early diagnosis and tailored therapies significantly improve outcomes. If you or a loved one experience symptoms like persistent swollen lymph nodes, consult a healthcare professional promptly.

Frequently Asked Questions

1. What is The Main Cause of Lymphoma?

Lymphoma’s exact cause is unknown, but factors like viral infections and chemical exposure increase risk.

2. How is Lymphoma Diagnosed?

A combination of physical exams, imaging tests, and biopsies is used for diagnosis.

3. Can Lymphoma Be Cured?

Many types of lymphoma, particularly Hodgkin’s lymphoma, have high cure rates with timely treatment.

4. What are The Early Symptoms of Lymphoma?

Early signs include enlarged lymph nodes, fever, and unexplained weight loss.

5. Is Lymphoma Hereditary?

While lymphoma is not typically hereditary, genetic predispositions may play a role in some cases.

6. Lymphoma is Treated Under Which Specialty and Care?

Lymphoma is primarily treated under the specialties of hematology and oncology. Care involves a multidisciplinary team, including hematologists, oncologists, radiologists, and specialized nurses, ensuring comprehensive treatment and management.
