An Unknown but Common Cancer Steadily Increasing

Lymphomas are malignant tumors developed from the lymphatic system. The latter consists of:

- a network of lymphatic vessels transporting in a transparent liquid, called the lymph, the defense cells of the body, the lymphocytes (subtype of white blood cells)

- lymph nodes and organs where these defense cells are manufactured and / or are found in large quantities: spleen, tonsils, thymus, lymphoid tissue associated with the mucous membranes (intestine, lung, etc.), bone marrow.

There are Two Major Types of Lymphoma

  • Hodgkin’s lymphoma
  • Non-Hodgkin’s lymphoma (NHL)

This cancer is the 6th worldwide in terms of incidence (5th in the USA) and NHL are the most frequent hemopathic malignancies (blood cancer) with an incidence rate of 13/100 000 inhabitants per year.

The clinical evolution and therapeutic options vary depending on the different types/subtypes of the disease.
