Recognize World Lymphoma Awareness Day

Lymphoma is any cancer that starts in the lymphatic system. The lymphatic system is a network of organs and vessels that moves a clear liquid called lymph around the body. This network is a key part of the body’s immune system. The lymphatic system helps filter out dead cells and other debris from the bloodstream. It also helps protect the body against germs, including bacteria and viruses.

Lymphoma can start in any part of the lymphatic system. Once cells in the lymphatic system, called lymphocytes, become abnormal, the cells often grow quickly and then divide in half to make more cells. Over time, the lymphoma cells in the lymphatic system can travel all over the body. These cells prevent healthy cells near them from working normally and make it difficult for the immune system to work properly. These cells also use nutrients and energy, causing healthy cells to starve.

St. Jude provides treatment for children with all types of lymphoma. The main two types of lymphoma are:

• Hodgkin lymphoma: This cancer starts in the lymph system (part of the immune system) and causes affected lymph nodes to get larger. This cancer may spread to the spleen, liver, bone marrow or lungs.
• Non-Hodgkin lymphoma: This is the group name for all types of lymphomas except Hodgkin lymphoma.
