Hodgkin's Lymphoma

Hodgkin's lymphoma, also known as Hodgkin's disease, is a cancer of the lymphatic system, which is part of your immune system.

In Hodgkin's lymphoma, cells in the lymphatic system grow abnormally and may spread beyond the lymphatic system. As Hodgkin's lymphoma progresses, it compromises your body's ability to fight infection. (source: Mayo Clinic)
