Hodgkin lymphoma basics

Review

Review

• The lymphatic system consists of lymph and

a network of vessels and organs. It helps kill

germs in the body and transports fluids to the

bloodstream.

• Lymphomas are cancers that start in

lymphocytes within the lymphatic system.

Hodgkin lymphoma starts in abnormal

lymphocytes called Reed-Sternberg cells or

lymphocyte-predominant cells.

• Hodgkin lymphoma often spreads from one

group of lymph nodes to the next. Over time,

it will spread to tissue and organs outside the

lymphatic system.

• An excisional biopsy removes the whole tumor

so that it can be tested for cancer.
