Hodgkin's Lymphoma
What is Hodgkin's Lymphoma?
Hodgkin's lymphoma is a type of cancer that starts in your lymphatic system. The lymphatic system is part of your immune system and helps fight infections. It includes lymph nodes, the spleen, bone marrow, and other organs that produce and store white blood cells.
In Hodgkin's lymphoma, white blood cells called lymphocytes grow abnormally and form tumors. These abnormal cells crowd out healthy cells and make it harder for your body to fight infections. The disease often starts in lymph nodes in your neck, chest, or underarms and can spread to other parts of your body.
Hodgkin's lymphoma is one of the most treatable forms of cancer, especially when found early. It differs from non-Hodgkin's lymphoma because it contains a specific type of abnormal cell called a Reed-Sternberg cell. About 8,000 people in the United States are diagnosed with Hodgkin's lymphoma each year.
Symptoms
- Swollen lymph nodes in the neck, armpits, or groin that are usually painless
- Persistent fatigue and low energy that does not improve with rest
- Fever that comes and goes without an obvious cause
- Night sweats that soak your sheets and clothing
- Unexplained weight loss of more than 10 pounds in 6 months
- Itchy skin without a visible rash
- Persistent cough or trouble breathing
- Chest pain or pressure
- Loss of appetite
- Pain in lymph nodes after drinking alcohol
Some people have no symptoms in the early stages. Others may experience what doctors call B symptoms, which include fever, night sweats, and weight loss. These symptoms often indicate more advanced disease.

Causes and risk factors
The exact cause of Hodgkin's lymphoma is not fully understood. It happens when lymphocytes develop genetic mutations that cause them to multiply uncontrollably. Certain risk factors increase your chances of developing this cancer. These include infection with the Epstein-Barr virus, which causes mononucleosis. Having a weakened immune system from HIV infection or immune-suppressing medications also raises risk. Family history plays a role, as having a sibling with Hodgkin's lymphoma increases your risk.
The disease is most common in people ages 20 to 40 and those over 55. Men are slightly more likely to develop Hodgkin's lymphoma than women. However, many people diagnosed with this cancer have no known risk factors. The condition is not caused by anything you did or did not do.
How it's diagnosed
Diagnosing Hodgkin's lymphoma requires several tests. Your doctor will start with a physical exam to check for swollen lymph nodes and other signs. Blood tests can show changes in your immune system and protein levels. Tests like protein electrophoresis can reveal abnormal protein patterns that suggest lymphoma. Elevated levels of certain biomarkers, including Interleukin-2 Receptor Alpha Chain, may indicate increased T-cell activation seen in this cancer.
The definitive diagnosis requires a biopsy. Your doctor will remove a sample of lymph node tissue and examine it under a microscope for Reed-Sternberg cells. Imaging tests like CT scans, PET scans, or X-rays help determine how far the cancer has spread. Your doctor may also perform a bone marrow biopsy to check if the cancer has reached your bone marrow. Talk to your doctor about which tests are right for you.
Treatment options
- Chemotherapy uses powerful drugs to kill cancer cells throughout your body
- Radiation therapy targets cancer cells in specific areas with high-energy beams
- Immunotherapy medications help your immune system recognize and attack cancer cells
- Targeted therapy drugs attack specific proteins on cancer cells
- Stem cell transplant may be needed if the cancer returns after initial treatment
- Eating a nutrient-dense diet with plenty of fruits, vegetables, and lean protein
- Staying physically active within your ability to maintain strength and energy
- Getting enough rest and managing stress during treatment
- Avoiding smoking and limiting alcohol to support your immune system
- Working closely with an oncologist who specializes in blood cancers
Frequently asked questions
The most common early sign is painless swelling of lymph nodes in your neck, armpits, or groin. You might also notice persistent fatigue, unexplained fever, or night sweats. Some people experience unexplained weight loss or itchy skin. Many people have no symptoms in the very early stages.
Blood tests alone cannot diagnose Hodgkin's lymphoma, but they provide important clues. Tests like protein electrophoresis can show abnormal protein patterns in your blood. Elevated levels of certain biomarkers like IL-2Ra may indicate increased immune activity. A lymph node biopsy is always needed for a definitive diagnosis.
Yes, Hodgkin's lymphoma is one of the most curable cancers. About 85% of people diagnosed with early-stage disease can be cured with treatment. Even people with advanced disease have cure rates of 60% to 70%. Early detection and modern treatment methods have made survival rates very high.
Young adults ages 20 to 40 and adults over 55 are at highest risk. People with a history of Epstein-Barr virus infection have increased risk. Those with weakened immune systems from HIV or immune-suppressing drugs are also more vulnerable. Having a sibling with Hodgkin's lymphoma increases your risk.
The main difference is the type of abnormal cell present. Hodgkin's lymphoma contains Reed-Sternberg cells, which are not found in non-Hodgkin's lymphoma. Hodgkin's lymphoma tends to spread in a more predictable pattern. It also generally has a better prognosis and responds well to treatment.
Treatment typically lasts 3 to 6 months for early-stage disease. More advanced cases may require 6 to 8 months or longer. The exact duration depends on the stage of cancer and your response to treatment. Your oncologist will create a personalized treatment plan based on your specific situation.
Yes, healthy lifestyle choices can support your body during treatment. Eating nutritious foods helps maintain strength and energy. Gentle exercise can reduce fatigue and improve mood. Getting enough sleep and managing stress support your immune system. Avoiding smoking and limiting alcohol are especially important.
Night sweats happen because cancer cells release chemicals that affect your body's temperature regulation. These sweats are often severe enough to soak your sheets and clothing. They are considered a B symptom and may indicate more active disease. Not everyone with Hodgkin's lymphoma experiences night sweats.
Yes, even early-stage Hodgkin's lymphoma requires treatment. The good news is that early-stage disease usually responds very well to treatment. You may need fewer chemotherapy cycles and smaller radiation fields than people with advanced disease. Your doctor will recommend the least intensive treatment that can cure your cancer.
Hodgkin's lymphoma can return in some cases, usually within the first 2 years after treatment. About 10% to 30% of people experience a relapse. Regular follow-up appointments and monitoring help catch any recurrence early. If the cancer returns, additional treatment options are available, including stem cell transplant.
