Description

Lymphocytes, which are white blood cells, are where lymphomas develop. Hodgkin Lymphoma (HL) and Non-Hodgkin Lymphoma (NHL) are the two main kinds of lymphoma. HL and NHL originate from many cell types. Knowing which form of lymphoma we have is crucial since they act, spread, and respond to treatment differently. Knowing about the lymphatic system is helpful for understanding what hodgkin lymphoma is (also known as the lymphatic system). The immune system, which assists in battling infections and various other disorders, includes the lymphatic system. The lymphatic system also aids in regulating the body's fluid circulation.

White blood cells known as lymphocytes make up the majority of the lymph system's cells. Lymphocytes come in two primary categories:

• B lymphocytes (B cells) produce antibodies, which aid in defending the body against pathogens (bacteria and viruses).

• T lymphocytes (T cells) come in a variety of forms. Certain T cells kill pathogens and aberrant cells in the body. Other T cells aid in accelerating or decelerating the activity of other immune system cells.

Hodgkin lymphoma in lymphoid tissues

Lymph nodes: Bean-sized clusters of lymphocytes and other immune system cells are called lymph nodes. They can be found throughout the body, including in the pelvis, belly, and the chest. A network of lymphatic vessels links them all together.

Lymph vessels: A system of minuscule tubes that connect lymph nodes and transport immune cells in a transparent fluid called lymph. These tubes resemble blood arteries in appearance. The body's lymph is gathered from all throughout and injected into the bloodstream.

Spleen: On the left side, beneath the lower ribs, is an organ called the spleen. A component of the immune system is the spleen. It produces immune system cells like lymphocytes. Additionally, it preserves healthy blood cells while removing bacteria, cell waste, and damaged blood cells.

Bone marrow: The fluid, spongy tissue found inside some bones is called bone marrow. There, new blood cells, some of which are lymphocytes, are produced.

Thymus: A small organ located in front of the heart and behind the upper portion of the breastbone is called the thymus. The growth of T lymphocytes depends on it.

Adenoids and tonsils: In the back of the throat, there are these clumps of lymph tissue. They aid in the production of antibodies that protect against ingested or inhaled pathogens.

Digestive tract: Lymph tissue can be found in the stomach, intestines, and numerous other organs.

Hodgkin lymphoma can begin practically anywhere; however it typically does so in the upper body's lymph nodes. The chest, neck, or under the arms are the most typical locations. Hodgkin lymphoma often spreads from lymph node to lymph node through the lymphatic system. Rarely, later on in the course of the illness, it can enter the bloodstream and spread to other organs such as the liver, lungs, and/or bone marrow.

Types of hodgkin lymphoma

Hodgkin lymphoma can develop, spread, and respond to treatment differently depending on the type of hodgkin lymphoma.

Classic hodgkin lymphoma: In affluent nations, more than 90% of instances of hodgkin lymphoma are caused by Classic Hodgkin Lymphoma (CHL). Reed-Sternberg cells are the cancer cells found in CHL. Typically, these cells are a subtype of B lymphocyte that is aberrant. People with CHL typically have enlarged lymph nodes that are surrounded by a significant number of healthy immune cells and only a few Reed-Sternberg cells. The majority of the lymph node swelling is brought on by these other immune cells.

Nodular lymphocyte-predominant hodgkin lymphoma: About 5% of instances of hodgkin lymphoma are Nodular Lymphocyte-Predominant Hodgkin Lymphoma (NLPHL). Large cells known as popcorn cells so named because they resemble popcorn which are subtypes of Reed-Sternberg cells are the cancer cells in NLPHL. These cells may alternatively be referred to as Lymphocytic and Histiocytic (L and H) cells. In the neck and under the arm, lymph nodes are where NLPHL typically begins. It can strike anyone at any age, although males are more likely to experience it than women. Compared to the traditional varieties, this sort of HL often grows more slowly and is handled differently.
