Lymphomas are types of blood cancers affecting cells of the immune system, called lymphocytes. There are many types of lymphomas. Generally they can be classified into one of two major categories: Hodgkin lymphoma and non-Hodgkin lymphomas.

Hodgkin Lymphoma

One of the more curable forms of lymphoma, Hodgkin’s Lymphoma is often cured after initial treatment. A smaller number of patients may have a relapse of the disease. In these cases, re-treatment is often successful. The most common sign of Hodgkin Lymphoma is one or more enlarged lymph node. Other symptoms may include fatigue, fever, night sweats, itching or weight loss.

Non-Hodgkin Lymphomas

There are many subtypes of non-Hodgkin Lymphomas (NHL). They are typically grouped into three distinct categories based on aggressiveness. These categories are indolent (or low-grade), aggressive (or intermediate-grade), and highly aggressive (or high-grade). Non-Hodgkin lymphomas can occur at any age and are often marked by enlarged lymph nodes, fever, and weight loss.
