an overreaction by the body to a particular antigen; also known as hypersensitivity
a severe response to a foreign substance such as a drug, food, insect venom, or chemical
a disease fighting protein caused by the immune system in response to the presence of a specific antigen
any substance such as a virus, bacterium, or toxin that the body regards as foreign
medication used to treat viral infections or to provide temporary immunity
an infection caused by a fungus of the genus Aspergillus
disorder of the immune system in which the body attacks itself
Medication that prevents or reduces the body's normal reactions to invasion by disease or by foreign tissues.
Treatment used to interfere with the ability of the immune system to respond to antigen stimulation.
Treatment of disease either by enhancing or repressing the immune response.
An infection caused by Epstein-Barr virus (one of the herpes viruses) that is characterized by fever, a sore throat, and enlarged lymph nodes.
Ductal carcinoma in situ
breast cancer at its earliest stage (stage 0) before the cancer has broken through the wall of the duct.
Invasive lobular carcinoma
cancer that starts in the milk glands (lobules), breaks through the wall of the gland and invades the fatty tissue of the breast.
Inguinal lymph nodes
are located in the inguinal (groin) area of the lower abdomen.
produced by the T cells and is a family of proteins released by cells when invaded by a virus. Also causes noninfected cells to form an antiviral protein that slows or stops viral multiplication.
form of sarcoma that is frequently associated with HIV and may affect the skin, mucous membranes, lymph nodes and internal organs
surgical removal of only the cancerous tissue and a margin of normal tissue.
inflammation of the lymph nodes: also known as swollen glands.
any disease process usually involving enlargement of the lymph nodes.

a benign abnormal collection of lymphatic vessels forming a mass.
an abnormal accumulation of fluid primarily in the legs and ankles that occurs when veins or lymph vessels do not drain properly
small white blood cells that bear the major responsibility for carrying out the activities of the immune system.
also referred to as enzyme-linked-immunosorbent assay; it is a blood test used to screen for the presence of HIV antibodies
An acute viral infection characterized by painful skin eruptions that follow by underlying route of the inflamed nerve; also known as shingles
is distinguished by the presence of Reed-Sternberg cells. These are large cancerous lymphocytes that are identified by microscopic examination of a biopsy specimen taken from an enlarged lymph node
Human immunodeficiency virus
A blood borne pathogen that invades and then progressively impairs or kills cells of the immune system
A condition that occurs when one or more parts of the immune system are deficient or missing
A type of antibody produced naturally by the body; synthetic immunoglobulis are administered as a post exposure preventative measure against certain viruses such as rabies and some types of hepatitis
A specialist in the study, diagnosis, and treatment of disorders of the immune system
produced by the T-cells; direct the immune response by signaling between the cells of the immune system
a general term applied to malignancies that develop in the lymphatic system.
a type of phagocycte that protects the body by ingesting invading cells and by interacting with other cells of the immune system.
the new cancer site that results from the spreading process
the process by which cancer spreads from one place to another.
a sarcoma of nervous system origin.
the term used to describe all lymphomas other than Hodgkin's lymphoma.
a specialist in diagnosing and treating malignant disorders such as tumors and cancer.
the study of the prevention, causes, and treatment of tumors and cancer.
an infection that attacks a person with a weakened immune system
a malignant tumor usually involving the upper shaft of long bones, the pelvis, or knee.
new tumor growth that can be benign or malignant

Drain the breast and upper arm.

agent that slows or stops the growth of bacteria
therapy using radioactive sources that are placed inside the body
any malignant tumor derived from epithelial tissue
cervical lymph nodes
located in the neck; drain the head and neck
one of a series of enzymes in the blood serum that are part of the immune response
a herpes-type virus that usually causes disease when the immune system is compromised
used for chemotherapy, are destructive to cells, stops reproduction of cancer cells.
an organism that lives on or in a host and causes harm to the host
An organism that causes disease
a cell that engulfs and digests debris and invading microorganisms
the process by which a cell engulfs foreign substances or other cells
an acute viral infection that is most commonly transmitted to humans by the bite or saliva of an infected animal.
is a malignant tumor of the retina that occurs predominantly in young children
small bacteria that live in lice, fleas, ticks, and mites that are transmitted to humans ex: Rocky Mountain Spotted Fever

malignant tumor that arises from connective tissue
spiral shaped bacteria ex: lyme disease
an abnormal enlargement of the spleen
hemorrhage of the spleen
bacteria growing in bunches (like grapes) ex: pneumonia & skin infections
bacteria that form a chain ex: pharyngitis
radiation therapy administered at a distance from the body
a ductless glandular organ at the base of the neck that produces lymphocytes and aids in producing immunity
western blot test
to confirm a positive result of the ELISA test (HIV)This blood test that has more accurate results than the ELISA test.
