LYMPHOMA - GENERAL



What is it?
Lymphoma is a cancer that develops in the departure of certain white blood cells. The term "lymphome" comes from the lymphocytes (variety of white blood cells) that are involved in our body's defenses against disease and infections. " They travel in a network called the lymphatic system.

When abnormal lymphocytes are produced, they accumulate and eventually form of Lymphoma (tumors) in the lymphoid tissue and especially in the lymph nodes.

The disease initially appears in a specific place, usually a lymph node. In rare cases, it can start elsewhere in the lymphatic system: in the spleen, liver, or bone marrow. The lymphatic vessels carry cancer cells to other lymph nodes. Finally, these cells can reach in the blood and spread throughout the body.

There are many types of lymphomas, fall into two categories:
Lymphoma (Hodgkin's disease) hodgkiniens
No (the most frequent) hodgkiniens, themselves divided lymphomas into two groups: indolent (to slow evolution)
aggressive (to rapidly changing)

Lymphoid tissue includes all lymph nodes and organs where the majority of lymphocytes and other cells of the immune system.

Lymph nodes affected by Lymphoma

Functioning of the lymphatic system
The lymphatic vessels are channels filled with lymph from tissues. Lymph is a clear liquid, result of a filtration of the blood, which carries waste from the body.

Also, the lymph contains white blood cells. Through the channels of diameter of more and more important, the lymph joined the blood circulation. Before she arrives in the blood, it crosses at least one lymph node.

Lymph nodes are the sewage of the lymphatic system: they make harmless pathogens, including bacteria and viruses. In addition, they filter the waste in the lymph. Lymph nodes can be found in various parts of the body:

in the neck
at the level of the armpits
along the trachea
near the lungs
near the intestine and in the back of the abdominal cavity
in the area of the basin
at the level of the groin
So-called lymphoid tissue all the lymph nodes and some present tissues at the level

of the throat (pharynx)
respiratory
of the spleen
of the bowel wall
the bone marrow
Lymphoid tissue contains a large number of white blood cells called lymphocytes.

Lymphocytes are produced in the bone marrow, lymph nodes and spleen. They circulate in the blood and lymph. Lymphocytes play an important role in the fight against microbes and the production of defensive substances.
