What Is Lymphoma? Types and Symptoms

Lymphoma is a type of blood cancer that begins in the lymphocytes — the white blood cells responsible for fighting infection. These cells are a core part of the lymphatic system and are found throughout the lymph nodes, spleen, thymus, and bone marrow. When lymphocytes undergo abnormal genetic changes, they begin to grow and multiply uncontrollably, forming tumors in the lymph nodes or other parts of the lymphatic system. Left undiagnosed, this abnormal growth can spread to other organs, which is why early recognition of symptoms plays a crucial role in successful treatment outcomes.

Types of Lymphoma

Lymphoma is broadly classified into two main types: Hodgkin lymphoma and Non-Hodgkin lymphoma. Both begin in the lymphocytes, but they differ in the specific type of cell involved, how the disease behaves, and how it responds to treatment.

Non-Hodgkin lymphoma is far more common and accounts for the majority of lymphoma cases diagnosed worldwide. It can develop from either B-cells or T-cells and includes several subtypes that vary widely in how quickly they progress — from slow-growing (indolent) to fast-growing (aggressive) forms.

Hodgkin lymphoma is less common and is identified by the presence of a specific abnormal cell called the Reed-Sternberg cell. It tends to spread in a more predictable, orderly pattern from one lymph node group to the next, which often makes it easier to stage and treat.

Because the two types involve different cells and progress differently, their symptoms, diagnostic approach, and treatment protocols also differ — making accurate diagnosis by an oncologist essential before starting treatment.

What Causes Lymphoma?

While the exact cause of lymphoma isn’t always clear, certain factors are known to increase risk:

• Age — Non-Hodgkin lymphoma is more common after age 60, while Hodgkin lymphoma typically appears between ages 15–40, or after 55.
• Weakened immune system — Conditions like HIV/AIDS or a history of organ transplantation can raise the risk.
• Autoimmune diseases — Disorders such as rheumatoid arthritis or Sjögren’s syndrome are associated with a higher likelihood of developing lymphoma.
• Viral infections — Exposure to viruses like Epstein-Barr virus, Hepatitis C, or HTLV-1 has been linked to certain lymphoma subtypes.

It’s important to note that having one or more risk factors doesn’t mean a person will definitely develop lymphoma — it simply means closer monitoring may be advisable.

Early Symptoms of Lymphoma

Lymphoma symptoms can be subtle at first and are often mistaken for common illnesses, which is why they’re frequently overlooked. Watch out for:

• Painless swelling in the lymph nodes — most often in the neck, armpit, or groin
• Persistent cough or breathlessness
• Unexplained fever that comes and goes
• Drenching night sweats
• Ongoing fatigue that doesn’t improve with rest
• Unintentional weight loss
• Persistent, unexplained itching of the skin

If you notice a combination of these symptoms lasting more than two to three weeks, it’s important not to self-diagnose or delay — timely evaluation by a specialist significantly improves treatment outcomes.

How Is Lymphoma Diagnosed and Treated?

Diagnosis typically begins with a physical examination followed by imaging tests (CT/PET scans) and a lymph node biopsy to confirm the type and subtype of lymphoma. Once confirmed, an oncologist creates a personalized treatment plan, which may include chemotherapy, immunotherapy, targeted therapy, or radiation — depending on the type, stage, and the patient’s overall health. Many patients today respond very well to modern treatment protocols, especially when the disease is caught early.

When Should You See an Oncologist?

If you’re experiencing persistent swelling in the lymph nodes along with fatigue, fever, or unexplained weight loss, it’s advisable to consult a qualified oncologist promptly rather than waiting for symptoms to worsen.

He completed his D.M. in Medical Oncology from the prestigious Tata Memorial Hospital, Mumbai, and continues to help patients navigate diagnosis and treatment with clarity and compassion.

Frequently Asked Questions

1. What is lymphoma in simple terms?

Lymphoma is a cancer that starts in the lymphocytes — white blood cells that are part of the body’s infection-fighting system. It causes these cells to grow uncontrollably, usually forming tumors in the lymph nodes.

2. What are the two main types of lymphoma?

The two main types are Hodgkin lymphoma and Non-Hodgkin lymphoma. Non-Hodgkin lymphoma is more common and includes several subtypes, while Hodgkin lymphoma is identified by the presence of Reed-Sternberg cells and tends to spread in a more predictable pattern.

3. What is the first sign of lymphoma?

The most common early sign is painless swelling of the lymph nodes, usually in the neck, armpit, or groin. This is often accompanied by fatigue, mild fever, or night sweats that persist for weeks.

4. Is lymphoma curable?

Many cases of lymphoma, especially when detected early, respond very well to treatment such as chemotherapy, immunotherapy, or radiation. Cure and remission rates vary depending on the type, stage, and the patient’s overall health.

5. At what age is lymphoma most common?

Non-Hodgkin lymphoma is more common in people over 60, while Hodgkin lymphoma typically appears between ages 15–40, or after 55.

6. Can lymphoma be mistaken for something else?

Yes, because early symptoms like fatigue, fever, and swollen glands overlap with common infections, lymphoma is sometimes mistaken for less serious illnesses. This is why symptoms lasting more than 2–3 weeks should be evaluated by a doctor.

7. What tests are used to diagnose lymphoma?

Diagnosis usually involves a physical examination, imaging tests such as CT or PET scans, and a lymph node biopsy to confirm the exact type and subtype of lymphoma.

8. When should I see an oncologist for lymphoma symptoms?

If you notice persistent swollen lymph nodes along with unexplained weight loss, fever, or fatigue, it’s best to consult an oncologist promptly rather than waiting for symptoms to progress.
