: A network of thin tubes that collect lymph
from different parts of the body and return it to the bloodstream.
Small, bean-shaped structures that filter lymph and store white blood cells that help fight
infection and disease. Lymph nodes are located along the network of lymph vessels
found throughout the body. Clusters of lymph nodes are found in the neck, underarm, abdomen, pelvis, and groin.
: An organ
that makes lymphocytes, filters the blood, stores blood cells, and destroys
old blood cells. It is located on the left side of the abdomen near the stomach.
: An organ
in which lymphocytes grow and multiply. The thymus is in the chest behind the breastbone.
: Two small
masses of lymph tissue
back of the throat. The tonsils make lymphocytes.
Hodgkin lymphoma can occur in both adults and children. Treatment for adults is different than treatment for children. Hodgkin lymphoma may also occur in patients who have acquired immunodeficiency syndrome
patients require special treatment.
the following PDQ summaries for more information:
Hodgkin lymphoma in pregnant
women is the same as the disease in nonpregnant women of childbearing age. However, treatment is different for pregnant women. This summary includes information about treating Hodgkin lymphoma during pregnancy.
There are two main types of Hodgkin lymphoma: classical and nodular lymphocyte-predominant.
Most Hodgkin lymphomas are the classical
type. The classical type is broken down into the following four subtypes:
Nodular sclerosing Hodgkin lymphoma.
Mixed cellularity Hodgkin lymphoma.
Lymphocyte depletion Hodgkin lymphoma.
Lymphocyte-rich classical Hodgkin lymphoma.
Age, gender, and Epstein-Barr infection can affect
the risk of adult Hodgkin lymphoma.
Anything that increases your risk of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesn't mean that you will not get cancer. Talk with your doctor if you think you may be at risk. Risk factors for adult
Hodgkin lymphoma include the following:
Tests that examine the lymph nodes are used to detect (find)
and diagnose adult Hodgkin lymphoma.
The following tests and procedures may be used:
and history: An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual. A history of the patient's past illnesses and treatments will also be taken.
Complete blood count
(CBC): A procedure in which a sample of blood is drawn and
checked for the following:
The number of red blood cells, white blood cells, and
The portion of the sample made up of red blood
Blood chemistry studies: A procedure in which a blood sample is checked to measure the amounts of certain substances released into the blood by
organs and tissues in the body. An unusual (higher or lower than normal) amount of a substance can be a sign
Sedimentation rate: A procedure in which a sample of blood is drawn and checked for the rate at which the red blood cells settle to the bottom of the test tube. The sedimentation rate is a measure of how much inflammation
is in the body. A higher than normal sedimentation rate may be a sign of lymphoma or another condition. Also called erythrocyte sedimentation rate, sed rate, or ESR.
Lymph node biopsy:
The removal of all or part of a lymph node. One of the following types of
biopsies may be done:
