Non-Hodgkin lymphoma is a type of cancer that begins in the lymphatic system, which is part of the body’s immune system. It involves the abnormal growth of lymphocytes, a type of white blood cell that helps fight infections.

There are many different types of non-Hodgkin lymphoma, and the disease can vary greatly in how fast it grows and how it is treated.

Understanding the Lymphatic System

The lymphatic system includes:

• Lymph nodes (small glands found throughout the body)

• Spleen

• Tonsils

• Bone marrow

• Lymphatic vessels

These components work together to help the body fight infection and remove waste.

Types of Non-Hodgkin Lymphoma

There are two main categories:

1. B-cell lymphomas – The most common type (e.g., diffuse large B-cell lymphoma, follicular lymphoma).

2. T-cell lymphomas – Less common and often more aggressive.

Each type can behave differently, so diagnosis and treatment depend on the specific kind of NHL.
