About this guide: This article is intended for general education and awareness, not medical advice. It cannot diagnose, prevent, or treat cancer. If you have questions about your health, please speak with a qualified healthcare professional.

01 / THE FOUNDATION

What exactly is lymphoma?

Lymphoma is a type of blood cancer that begins in lymphocytes, a group of white blood cells that help protect the body from infection and disease.

These cells are part of the lymphatic system, a network of vessels, nodes, and organs distributed throughout the body. This network supports immune defenses and helps maintain fluid balance.

When lymphocytes become cancerous, they can multiply and accumulate in lymph nodes or other tissues. Because lymphatic tissue exists throughout the body, lymphoma can develop in many different locations.

Lymphoma is not just one disease.

There are many subtypes with very different behaviors. Some grow slowly and may not initially require treatment. Others progress quickly and need prompt medical care.

NETWORK / 01

Lymph nodes

THE BODY'S IMMUNE CHECKPOINTS

Lymph nodes are small, bean shaped structures that filter lymph, a fluid containing immune cells and other substances. They help immune cells recognize and respond to germs.

Groups of lymph nodes are found throughout the body, including the neck, armpits, chest, abdomen, and groin.

Connection to lymphoma: Cancerous lymphocytes may accumulate in nodes, sometimes causing them to enlarge.

THE CELLS AT THE CENTER

What is a lymphocyte?

Lymphocytes are white blood cells that play important roles in immune defense. They include B cells, T cells, and natural killer (NK) cells.

B cells help produce antibodies. T cells perform different immune functions, including coordinating responses and destroying certain infected or abnormal cells. NK cells can attack some infected or abnormal cells.

Lymphoma develops when one of these cell populations becomes malignant. Different lymphoma subtypes arise from different lymphocyte lineages.

Conceptual illustrations · Actual cell types require laboratory identification

02 / KNOWING THE DIFFERENCES

Two main groups. Many different diagnoses.

Lymphomas are broadly grouped into Hodgkin lymphoma and non-Hodgkin lymphoma. These names describe categories of cancers, not two diseases that always behave the same way.

The exact subtype matters because it helps guide treatment and provides information about how the illness may behave.

01 / HODGKIN LYMPHOMA

Hodgkin lymphoma

HL · OFTEN ASSOCIATED WITH VIOLET

Hodgkin lymphoma is a distinct group of lymphoid cancers. Most cases are classic Hodgkin lymphoma, typically characterized by abnormal cells called Reed–Sternberg cells in a characteristic tissue background.

It often involves lymph nodes in the neck or chest. Many people can be cured with treatment, although outcomes depend on disease and patient factors.

There are several subtypes of classic Hodgkin lymphoma and a rarer nodular lymphocyte-predominant form, which is managed differently and classified differently in some modern systems.

Diagnostic clue: Characteristic cells and tissue markers

02 / NON-HODGKIN LYMPHOMA

Non-Hodgkin lymphoma

NHL · OFTEN ASSOCIATED WITH LIME GREEN

Non-Hodgkin lymphoma is a large collection of cancers that develop from lymphocytes. Most NHL cases arise from B cells, although T-cell and NK-cell lymphomas also occur.

Some subtypes grow slowly, while others progress rapidly. NHL can begin in lymph nodes or in other tissues, such as the stomach, skin, or intestines.

Because there are many subtypes, treatment and prognosis can vary considerably.

Diagnostic clue: Cell lineage, tissue features and markers

Some examples of non-Hodgkin lymphoma

These examples illustrate why two people with lymphoma might have entirely different treatment experiences.

OFTEN AGGRESSIVE

Diffuse large B-cell lymphoma

Often abbreviated DLBCL, this is a common fast-growing NHL subtype. It typically requires prompt treatment and can be curable in many cases.

OFTEN INDOLENT

Follicular lymphoma

Typically grows slowly. Some people are monitored for a period before treatment is needed. It can respond well to therapy but may return.

RELATED CONDITIONS

CLL / SLL

Chronic lymphocytic leukemia and small lymphocytic lymphoma are closely related forms of the same disease, distinguished mainly by where cancer cells are found.

MANY ADDITIONAL TYPES

T-cell and other lymphomas

These include several distinct diseases, with differing growth rates, affected tissues, and treatment options.

◷

Indolent lymphoma

Often grows slowly. Treatment may be deferred in selected cases under medical supervision.

↗

Aggressive lymphoma

Often grows more quickly and usually needs prompt treatment. Some aggressive lymphomas can be cured.

Important: Faster growing doesn't automatically mean less treatable, and slower-growing doesn't always mean curable. The exact diagnosis makes the difference.

03 / THE SCIENCE, SIMPLIFIED

How does someone develop lymphoma?

Lymphoma develops when certain lymphocytes acquire changes that disrupt normal controls over their growth, survival, or activity. These cells may begin multiplying abnormally and accumulating in lymphatic tissues or organs.

Many of these changes develop during life rather than being directly inherited. In most individual cases, there is no way to identify one exact cause.

When healthy cell behavior changes

A conceptual illustration of cancer development, not a fixed pathway for every lymphoma.

STEP 01

Normal lymphocyte

A healthy immune cell follows the body's signals for growth, activity, and survival.

STEP 02

Genetic changes

Acquired DNA alterations can affect how a lymphocyte grows or survives.

STEP 03

Abnormal growth

Altered cells multiply or survive abnormally and may accumulate.

STEP 04

Lymphoma develops

Cancer cells can build up in lymph nodes or other tissues and affect normal function.

What can increase the risk?

Risk factors differ by lymphoma subtype. Having a risk factor doesn't mean someone will develop cancer, and many people diagnosed with lymphoma have no known risk factors.

◎

Age & family history

Risk varies with age and subtype. Hodgkin lymphoma occurs more often in young adults and older adults, while many NHL types are more common later in life. Certain family histories can also increase risk.

✳

Immune system conditions

Some immune deficiencies, autoimmune disorders, or medications that suppress the immune system can increase the risk of certain lymphomas.

⌁

Certain infections

Epstein–Barr virus, HIV, and some other infections are associated with particular lymphomas. For example, H. pylori infection is linked to some lymphomas of the stomach.

◇

Other disease specific factors

Some lymphoma subtypes have additional recognized associations. Researchers continue studying how genetic changes, immune regulation, infections, and environmental exposures interact.

Lymphoma is not contagious. You cannot catch lymphoma by hugging someone, sharing food, or being near a person with cancer. Even when an infection is associated with lymphoma risk, the cancer itself isn't passed through ordinary contact.

04 / POSSIBLE SIGNS & SYMPTOMS

What might lymphoma feel like?

Symptoms vary depending on the type of lymphoma, its location, and how quickly it is growing. Some people initially feel completely well, while others develop persistent changes.

Importantly, most swollen lymph nodes are caused by something other than lymphoma, especially infections. The symptoms below are informational, not a diagnostic checklist.

◌

Swollen lymph nodes

Enlarged, often painless nodes in the neck, armpits, or groin.

☼

Unexplained fever

Recurring or persistent fever without an apparent explanation.

☾

Drenching night sweats

Sweating heavily during sleep, sometimes enough to soak clothing or bedding.

↘

Unintentional weight loss

Weight loss that occurs without a deliberate change in diet or activity.

✧

Persistent fatigue

Unusual tiredness, weakness, or reduced energy that doesn't improve as expected.

≋

Other changes

Itching, abdominal fullness, cough, or chest discomfort in some cases.

A TERM YOU MIGHT HEAR

What are “B symptoms”?

In lymphoma care, B symptoms refers to a specific group of systemic symptoms: unexplained fever, drenching night sweats, and significant unintentional weight loss. Clinicians use this information in disease assessment and, in some lymphoma types, staging.

These symptoms can also occur with many non-cancerous conditions. Having them does not mean someone has lymphoma.

When should symptoms be evaluated?

Persistent, enlarging, or unexplained lymph node swelling and other ongoing symptoms deserve a medical assessment. New or severe difficulty breathing requires urgent medical attention. This guide cannot determine the cause of an individual's symptoms.

05 / FROM QUESTIONS TO ANSWERS

How is lymphoma diagnosed?

A lymphoma diagnosis requires more than noticing an enlarged lymph node or seeing an abnormal blood result. Doctors must identify the cancer cells and determine the exact subtype, often by examining affected tissue.

Medical history & examination

A clinician reviews symptoms, health history, and possible risk factors, then examines lymph nodes and other relevant areas. Because infections commonly cause swollen nodes, the context matters.

A tissue biopsy

Removing all or part of an affected lymph node or another suspicious tissue often provides the information needed to diagnose lymphoma. A core needle biopsy may sometimes be used, but smaller samples can be insufficient.

Pathology & specialized testing

Specialists examine the cells and tissue arrangement. Tests such as immunohistochemistry, flow cytometry, and genetic or molecular analysis can help identify the lymphoma subtype.

Imaging & disease assessment

CT or PET/CT scans, blood tests, and sometimes other procedures help determine where lymphoma is present, assess organ function, and guide a treatment plan. Not everyone requires the same tests.

A blood test alone cannot reliably diagnose or rule out lymphoma.

A complete blood count can help evaluate overall health and reveal changes, but a normal result does not exclude lymphoma. Tissue examination is generally essential to confirm the diagnosis.

UNDERSTANDING EXTENT OF DISEASE

What does staging mean?

Staging describes where lymphoma is found in the body. Some types use a system from Stage I through IV, based on the distribution of affected lymph nodes and organs.

But lymphoma staging isn't identical to how staging is interpreted for many solid tumors. The subtype, symptoms, health factors, and treatment response also influence prognosis. A stage number alone doesn't tell the full story.

Illustrative only · Not a tool for assigning stage

06 / TREATMENT & CARE

What does treatment look like?

There is no single treatment that works for every lymphoma. The care team considers the exact subtype, extent of disease, symptoms, overall health, previous treatments, and a person's priorities.

01 /

Active surveillance

Some people with slow growing lymphoma may be monitored with regular medical follow-up until treatment becomes necessary.

02 /

Chemotherapy

Medicines that damage or disrupt cancer cells are used for many lymphoma types, sometimes combined with other therapies.

03 /

Immunotherapy

Certain antibodies and other immune based treatments help the immune system recognize or attack lymphoma cells.

04 /

Targeted therapies

Selected medicines target particular proteins or pathways involved in the growth and survival of lymphoma cells.

05 /

Radiation therapy

Radiation may be used in selected cases to treat lymphoma in defined areas or to help relieve certain symptoms.

06 /

Advanced & supportive care

CAR T-cell therapy, stem cell transplantation, and other treatments may be options for particular patients. Supportive care remains important throughout.

BEYOND THE RIBBON

Awareness creates understanding.
Compassion creates connection.

Lymphoma can affect people's lives in very different ways. One person may be receiving intensive treatment while another is living with a slower growing diagnosis under close observation.

Supporting someone begins with recognizing their individual experience, rather than assuming that everyone with lymphoma faces the same challenges.

01 / LISTEN

Listen without comparisons.

Every diagnosis is different. Avoid comparing someone else's experience, prognosis, or treatment. Make space for their feelings without pressuring them to be positive.

02 / SHOW UP

Offer practical support.

Help with errands, transportation, meals, household tasks, or simply spending time together. Ask what would be useful and respect someone's boundaries.

03 / EDUCATE

Share reliable information.

Support awareness by learning about the differences between lymphoma subtypes and sharing medically reviewed resources, not unverified cures or assumptions about survival.

04 / PARTICIPATE

Explore opportunities to help.

Consider supporting legitimate lymphoma research or patient service organizations. Eligible people can also explore blood or stem cell donation through official donor programs.

INTERACTIVE / MYTHS & FACTS

Let's separate the myths from the science.

Some misconceptions about lymphoma are surprisingly common. Select each question to reveal the facts.

01 Does every swollen lymph node mean cancer?

MYTH / MOST ARE NOT CANCER

No. Lymph nodes frequently enlarge in response to infections and other noncancerous conditions. Swelling alone cannot diagnose lymphoma. Nodes that persist, grow, or occur with other unexplained symptoms should be assessed by a healthcare professional.

02 Can you catch lymphoma from another person?

MYTH / NOT CONTAGIOUS

No. Lymphoma is cancer, not a contagious illness. It cannot be transmitted by everyday contact. Some infections are associated with higher risk for certain lymphomas, but infection related risk is not the same as spreading the cancer itself.

03 Does a lymphoma diagnosis always mean immediate chemotherapy?

MYTH / TREATMENT VARIES

No. Some indolent lymphomas can be monitored without immediate treatment when the patient has no concerning symptoms or other indications for therapy. Other types require prompt treatment. Options extend beyond chemotherapy and depend on the exact diagnosis.

04 Are Hodgkin and non-Hodgkin lymphoma basically identical?

MYTH / DISTINCT DISEASE GROUPS

No. Both are lymphoid cancers, but they differ in cell features, subtype classifications, and treatment approaches. Non-Hodgkin lymphoma alone contains many distinct diseases with widely varying outcomes.

05 Does a normal blood test rule out lymphoma?

MYTH / BLOOD TESTS ARE NOT DEFINITIVE

No. Blood tests can provide useful medical information, but a person may have lymphoma without obvious changes in a routine blood count. Confirmation generally requires examination of affected tissue and subtype specific testing.

THE HUMAN SIDE OF A DIAGNOSIS

Living with lymphoma doesn't always look the same.

For some people, lymphoma treatment happens over a relatively defined period. Others may live with a slower-growing disease that requires years of follow-up, intermittent treatment, or continued monitoring.

Even after successful treatment, there may be ongoing appointments, side effects, anxiety about recurrence, or a need to adjust to life after cancer. Some people also experience long-term physical or emotional effects.

And for those whose lymphoma is being monitored rather than immediately treated, living with a known diagnosis can bring its own uncertainty.

Support shouldn't disappear simply because active treatment has ended, or because treatment hasn't started yet.

Symbolic artwork · Every experience is individual

KNOWLEDGE · COMPASSION · COMMUNITY

There is more to every diagnosis than its name.

Behind every lymphoma diagnosis is a person whose life is more than a test result, a stage, or a treatment plan. Understanding the disease helps us appreciate the differences between these experiences, while recognizing what they share: the importance of support, research, and being heard.

Awareness can begin with something small. A meaningful conversation. A resource shared. An awareness ribbon worn in someone's honor.

And it can continue long after an awareness month has passed.

Keep learning. Keep listening. Keep showing up. WITH CARE, PIN HIVE
