Hodgkin lymphoma (formerly called Hodgkin’s disease) is a type of cancer that develops in the lymphatic system, an important part of your immune system. It begins when certain white blood cells called lymphocytes grow abnormally and multiply uncontrollably.

Unlike many other cancers, Hodgkin lymphoma is considered one of the most treatable and curable cancers, especially when diagnosed in its early stages. Modern treatments have significantly improved survival rates, allowing many people to live long, healthy lives after treatment.

In this guide, you’ll learn what Hodgkin lymphoma is, its symptoms, causes, diagnosis, treatment options, and outlook.

What Is the Lymphatic System?

The lymphatic system is a network of vessels, lymph nodes, and organs that helps your body:

Fight infections
Remove waste and excess fluid
Support immune function

Major parts of the lymphatic system include:

Lymph nodes
Spleen
Bone marrow
Thymus
Tonsils
Lymphatic vessels

Because lymph tissue exists throughout the body, Hodgkin lymphoma can develop in multiple locations.

What Is Hodgkin Lymphoma?

Hodgkin lymphoma is a cancer that usually starts in the lymph nodes, most commonly in the:

Neck
Chest
Underarms

A defining feature of Hodgkin lymphoma is the presence of Reed-Sternberg cells, which are large abnormal B lymphocytes visible under a microscope. Their presence helps distinguish Hodgkin lymphoma from non-Hodgkin lymphoma.

The disease often spreads from one group of lymph nodes to nearby lymph nodes in a predictable pattern.

Types of Hodgkin Lymphoma

There are two main types.

1. Classical Hodgkin Lymphoma (CHL)

This accounts for approximately 90–95% of cases.

Subtypes include:

Nodular sclerosis
Mixed cellularity
Lymphocyte-rich
Lymphocyte-depleted

2. Nodular Lymphocyte-Predominant Hodgkin Lymphoma (NLPHL)

This is much less common.

Characteristics include:

Slow-growing
Different cancer cells than classical Hodgkin lymphoma
Often treated differently
Generally has an excellent prognosis

Symptoms of Hodgkin Lymphoma

Many people first notice a painless swollen lymph node.

Common symptoms include:

Swollen Lymph Nodes

Usually found in:

Neck
Armpit
Groin
Above the collarbone

These swollen nodes are typically painless.

Persistent Fatigue

Feeling unusually tired that doesn’t improve with rest.

Fever

Recurring or unexplained fever without an obvious infection.

Night Sweats

Heavy sweating during sleep that may soak clothing or bedding.

Unexplained Weight Loss

Losing more than 10% of body weight over six months without trying.

Itchy Skin

Some individuals experience severe itching without a visible rash.

Chest Symptoms

If lymph nodes in the chest enlarge, they may cause:

Persistent cough
Chest discomfort
Shortness of breath

Loss of Appetite

Reduced appetite may accompany advanced disease.

What Are “B Symptoms”?

Doctors pay special attention to three symptoms called B symptoms, which can indicate more active disease:

Fever above 100.4°F (38°C)
Drenching night sweats
Unexplained weight loss

These symptoms help determine the stage and treatment approach.

Causes of Hodgkin Lymphoma

The exact cause remains unknown.

Researchers believe Hodgkin lymphoma develops after genetic changes occur in lymphocytes, causing them to multiply uncontrollably.

Risk Factors

Several factors may increase risk.

Age

Hodgkin lymphoma is most common in:

Young adults (15–35 years)
Adults over 55 years

Epstein-Barr Virus (EBV)

Previous infection with EBV (which causes mononucleosis) may increase the risk.

Family History

Having a close relative with Hodgkin lymphoma slightly raises risk.

Weakened Immune System

Risk is higher in people with:

HIV infection
Organ transplants
Certain immune disorders

Male Sex

Some forms occur slightly more often in men.

How Is Hodgkin Lymphoma Diagnosed?

Diagnosis usually involves several tests.

Physical Examination

Your healthcare provider checks for:

Enlarged lymph nodes
Enlarged spleen
Enlarged liver

Blood Tests

Blood work may evaluate:

Blood cell counts
Liver function
Kidney function
Signs of infection or inflammation

Lymph Node Biopsy

This is the most important test.

Doctors remove all or part of an enlarged lymph node to examine it under a microscope.

Finding Reed-Sternberg cells confirms classical Hodgkin lymphoma.

Imaging Tests

Imaging helps determine how far the cancer has spread.

Common tests include:

CT scan
PET scan
MRI (occasionally)

Bone Marrow Biopsy

This test may be needed if doctors suspect the lymphoma has spread to the bone marrow.

Stages of Hodgkin Lymphoma

Doctors classify Hodgkin lymphoma into four stages.

Stage I

Cancer affects one lymph node region.

Stage II

Cancer affects two or more lymph node regions on the same side of the diaphragm.

Stage III

Cancer is found on both sides of the diaphragm.

Stage IV

Cancer has spread to organs such as:

Liver
Bone marrow
Lungs

Treatment Options

Treatment depends on:

Stage
Type
Age
Overall health
Symptoms

Common treatments include:

Chemotherapy

Chemotherapy is the main treatment for most patients.

It uses medicines to destroy cancer cells throughout the body.

Radiation Therapy

High-energy radiation targets lymphoma cells in specific areas.

Radiation may be used after chemotherapy for early-stage disease.

Targeted Therapy

Some patients receive medicines that attack specific cancer cell proteins while minimizing damage to healthy cells.

Immunotherapy

Checkpoint inhibitors help the immune system recognize and destroy cancer cells.

They are often used for relapsed or treatment-resistant Hodgkin lymphoma.

Stem Cell Transplant

Patients whose lymphoma returns after treatment may benefit from:

Autologous stem cell transplant
Allogeneic stem cell transplant (selected cases)

Possible Side Effects of Treatment

Treatment side effects vary but may include:

Fatigue
Hair loss
Nausea
Low blood cell counts
Increased infection risk
Fertility concerns
Long-term heart or lung complications (depending on treatment)

Doctors carefully monitor patients to reduce these risks.

Survival Rate and Prognosis

Hodgkin lymphoma has one of the highest cure rates among cancers.

Factors affecting prognosis include:

Stage at diagnosis
Age
Overall health
Response to treatment

Many people diagnosed with early-stage Hodgkin lymphoma achieve long-term remission or are cured. Even advanced-stage disease can often be treated successfully with modern therapies.

Can Hodgkin Lymphoma Be Prevented?

There is currently no proven way to prevent Hodgkin lymphoma.

However, maintaining overall health may support your immune system by:

Eating a balanced diet
Exercising regularly
Avoiding tobacco
Limiting alcohol
Managing chronic illnesses
Attending routine medical checkups

When Should You See a Doctor?

Seek medical evaluation if you experience:

Swollen lymph nodes lasting longer than two weeks
Persistent fever
Night sweats
Unexplained weight loss
Constant fatigue
Ongoing cough or chest discomfort
Unexplained itching

Early diagnosis improves treatment success.

Frequently Asked Questions (FAQs)

Is Hodgkin lymphoma curable?

Yes. Hodgkin lymphoma is considered one of the most curable cancers, especially when diagnosed early and treated appropriately.

Is Hodgkin lymphoma the same as non-Hodgkin lymphoma?

No. They are different diseases. Hodgkin lymphoma is identified by the presence of Reed-Sternberg cells, while non-Hodgkin lymphoma includes many different lymphoma subtypes without these cells.

Is Hodgkin lymphoma hereditary?

Most cases are not inherited. Although a family history may slightly increase the risk, the majority of people diagnosed have no close relatives with the disease.

Does Hodgkin lymphoma spread quickly?

It often spreads in a predictable pattern from one lymph node group to nearby nodes. The speed of progression varies depending on the subtype and individual factors.

Can Hodgkin lymphoma come back after treatment?

Yes. While many people are cured, some experience a recurrence. Fortunately, effective treatment options are available for relapsed disease.
