What is lymphoma ?
The term lymphoma includes various types of lymphatic system cancers. The lymphatic system is part of the human immune system, which helps our body to defend primarily against infections.
Lymphoma develops when one or more errors occur on the lymphocyte level, leading to the production of abnormal cells that proliferate or live much longer than healthy lymphocytes. Lymphoma most often affects lymphatic ganglions but could also develop in all parts of the body. Cancerous lymphocytes, such as healthy lymphocytes, develop in a variety of locations in the body including the lymph nodes, spleen, bone marrow or other organs.
There are many lymphomas. There are two main groups :
- Hodgkin lymphomas (HO)
- non-Hodgkin lymphomas (NOHO).
There are over 100 different types of lymphomas in the latter group. All these diseases manifest and behave noticeably differently, so they require an adapted treatment.
