Hodgkin Lymphoma is a type of cancer affecting the Lymphatic System . Hodgkin Lymphoma is caused by the abnormal duplication ofB-lymphocytes, they will then start to collect in areas of the lymphatic system such as lymph nodes, most commonly leading to visible lumps in the neck, but lumps could also be visible in the groin or armpit]. There are 4 different stages that determine how far the cancer has spread, starting at Stage 1 where there is one group of Hodgkin lymphoma containing lymph nodes or one body organ affected. Leading up towards stage 4 where the cancer has spread to body organs, most likely the liver, bones or lungs.
Not to be confused with Non-Hodgkin Lymphoma.
