Lymphoma
Lymphoma is a type of blood cancer that develops in the lymphatic system and affects white blood cells called lymphocytes. The lymphatic system is an important part of the immune system and helps the body fight infections and diseases. :contentReference[oaicite:1]{index=1}
Lymphoma occurs when lymphocytes grow abnormally and multiply uncontrollably. It can affect lymph nodes, spleen, bone marrow, blood, and other organs of the body. :contentReference[oaicite:2]{index=2}
Overview
The lymphatic system includes:
- Lymph nodes
- Lymph vessels
- Spleen
- Bone marrow
- Tonsils
- Thymus gland
Lymphoma is considered one of the most common forms of blood cancer. It can occur in both children and adults. :contentReference[oaicite:3]{index=3}
Types of Lymphoma
There are two major categories of lymphoma:
Hodgkin Lymphoma
Hodgkin lymphoma is identified by the presence of abnormal cells known as Reed–Sternberg cells. It is considered highly treatable in many cases. :contentReference[oaicite:4]{index=4}
Non-Hodgkin Lymphoma
Non-Hodgkin lymphoma (NHL) includes a large group of lymphatic cancers that do not contain Reed–Sternberg cells. NHL is more common than Hodgkin lymphoma. :contentReference[oaicite:5]{index=5}
Causes and Risk Factors
The exact cause of lymphoma is not fully known, but several factors may increase risk:
- Weak immune system
- Family history of lymphoma
- Certain viral infections
- Exposure to chemicals or radiation
- Increasing age
- Autoimmune diseases
Genetic mutations in lymphocytes can lead to uncontrolled growth of abnormal cells. :contentReference[oaicite:6]{index=6}
Symptoms
Common symptoms of lymphoma include:
- Swollen lymph nodes
- Fever
- Night sweats
- Fatigue
- Unexplained weight loss
- Persistent cough
- Itching
- Shortness of breath
Swollen lymph nodes are usually painless and may occur in the neck, armpits, or groin. :contentReference[oaicite:7]{index=7}
Diagnosis
Doctors use several methods to diagnose lymphoma:
- Physical examination
- Blood tests
- Lymph node biopsy
- Bone marrow examination
- CT scan
- PET scan
- MRI scan
Accurate diagnosis is important because lymphoma has many subtypes requiring different treatments. :contentReference[oaicite:8]{index=8}
Treatment
Treatment depends on the type and stage of lymphoma.
Common treatments include:
- Chemotherapy
- Radiation therapy
- Immunotherapy
- Targeted therapy
- Stem cell transplant
Many forms of lymphoma are treatable and some are curable with early diagnosis and proper medical care. :contentReference[oaicite:9]{index=9}
Prevention
There is no guaranteed way to prevent lymphoma, but maintaining a healthy immune system and avoiding harmful chemical exposure may reduce certain risks.
Lymphoma Research
Modern research in immunotherapy, CAR T-cell therapy, and targeted medicines has significantly improved lymphoma treatment outcomes. :contentReference[oaicite:10]{index=10}
