TermDefinition
acquired immunodeficiency syndrome is a chronic, potentially life-threatening condition caused by the human immunodeficiency virus (HIV)
allergen a substance that causes an allergic reaction.
anaphylaxis an acute allergic reaction to an antigen (e.g., a bee sting) to which the body has become hypersensitive.
antibody a blood protein produced in response to and counteracting a specific antigen.
antigen a toxin or other foreign substance that induces an immune response in the body, especially the production of antibodies.
antiviral (chiefly of a drug or treatment) effective against viruses.
aspergillosis a condition in which certain fungi infect the tissues. It most commonly affects the lungs, owing to inhalation of spores from moldy hay, and is then informally called farmer's lung.
autoimmune disorder in which the body produces antibodies that attack its own tissues, leading to the deterioration and in some cases to the destruction of such tissue.
axillary lymph nodes (20 to 49 in number) drain lymph vessels from the lateral quadrants of the breast, the superficial lymph vessels from thin walls of the chest and the abdomen above the level of the navel, and the vessels from the upper limb.
bacilli a rod-shaped bacterium. a disease-causing bacterium.
bacteria a member of a large group of unicellular microorganisms that have cell walls but lack organelles and an organized nucleus, including some that can cause disease.
bactericide a substance that kills bacteria.
bacteriostatic agent or bacteriostat, abbreviated Bstatic, is a biological or chemical agent that stops bacteria from reproducing, while not necessarily killing them otherwise.
brachytherapy the treatment of cancer, especially prostate cancer, by the insertion of radioactive implants directly into the tissue.
carinoma a cancer arising in the epithelial tissue of the skin or of the lining of the internal organs.
cervical lymph nodes refers to lymphadenopathy of the cervical lymph nodes (the glands in the neck). The term lymphadenopathy strictly speaking refers to disease of the lymph nodes, often however the term refers to enlargement of the lymph nodes.
complement a thing that completes or brings to perfection.
cytomegalovirus a kind of herpesvirus that usually produces very mild symptoms in an infected person but may cause severe neurological damage in people with weakened immune systems and in the newborn.
cytotoxic toxic to living cells.
ductal carcinoma in situ is the presence of abnormal cells inside a milk duct in the breast. DCIS is considered the earliest form of breast cancer.
elisa enzyme-linked immunosorbent assay, an immunological assay technique making use of an enzyme bonded to a particular antibody or antigen.
herpes oster a herpesvirus that causes shingles and chickenpox.
hodgkin' disease is a type of lymphoma. Lymphoma is a cancer of a part of the immune system called the lymph system
human immunodeficiency virus is a virus that attacks the immune system, the body's natural defense system.
immunodeficiency disorder is a state in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent.
immunoglobulin any of a class of proteins present in the serum and cells of the immune system, that function as antibodies.
immunologist is a branch of biology that covers the study of immune systems in all organisms.
immunosuppressant An agent that can suppress or prevent the immune response
immunosuppression the partial or complete suppression of the immune response of an individual. It is induced to help the survival of an organ after a transplant operation.
immunotheraphy the prevention or treatment of disease with substances that stimulate the immune response.
infectious mononucleosis an infectious viral disease characterized by swelling of the lymph glands and prolonged lassitude.
infiltrating ductal carcinoma is cancer that began growing in the duct and has invaded the fatty tissue of the breast outside of the duct. IDC is the most common form of breast cancer, representing 80 percent of all breast cancer diagnoses.
infiltrating lobular carcinoma is a type of breast cancer that begins in the milk-producing glands (lobules) of the breast.
inguinal lymph nodes any of the superficial lymphatic nodes of the groin made up of two more or less distinct groups of which one is disposed along the inguinal ligament and the other about the saphenous opening.
interferon a protein released by animal cells, usually in response to the entry of a virus, that has the property of inhibiting virus replication.
Kaposi's sarcoma a form of cancer involving multiple tumors of the lymph nodes or skin, occurring chiefly in people with depressed immune systems, e.g., as a result of AIDS.
lumpectomy a surgical operation in which a lump is removed from the breast, typically when cancer is present but has not spread.
lymphadenitis inflammation of the lymph nodes.
lymphadenitis inflammation of the lymph nodes.
lymphadenopathy a disease affecting the lymph nodes.
lymphangiogram is a special x-ray of the lymph nodes and lymph vessels.
lymphangioma are malformations of the lymphatic system characterized by lesions that are thin-walled cysts; these cysts can be macroscopic, as in a cystic hygroma, or microscopic.
lymphedema is a condition of localized fluid retention and tissue swelling caused by a compromised lymphatic system, which normally returns interstitial fluid to the thoracic duct, then the bloodstream.
lymphocytes a form of small leukocyte (white blood cell) with a single round nucleus, occurring especially in the lymphatic system.
lymphokines a substance produced by lymphocytes, such as interferon, that acts upon other cells of the immune system, e.g., by activating macrophages.
lymphoma cancer of the lymph nodes.
macrophage a large phagocytic cell found in stationary form in the tissues or as a mobile white blood cell, especially at sites of infection.
meastasis the development of secondary malignant growths at a distance from a primary site of cancer.
metastasize (of a cancer) spread to other sites in the body by metastasis.
moniliasis Yeast infection of the mouth and throat caused by a fungus formerly called Monilia, now known as Candida albicans.
metastasize (of a cancer) spread to other sites in the body by metastasis.
myoma A tumor of muscle. Myoma can refer specifically to a benign tumor of uterine muscle, also called a leiomyoma or a fibroid.
myosarcoma is a malignant muscle tumor. Leiomyosarcoma is sarcoma of smooth muscle, and rhabdomyosarcoma is sarcoma of striated muscle
neoplasm a new and abnormal growth of tissue in some part of the body, especially as a characteristic of cancer.
neuroblastoma a malignant tumor composed of neuroblasts, most commonly in the adrenal gland.
non-hodgkins lymphoma a form of malignant lymphoma distinguished from Hodgkin's disease only by the absence of binucleate giant cells.
oncologist a medical practitioner qualified to diagnose and treat tumors.
oncology the study and treatment of tumors.
opportunistic infection is an infection caused by pathogens (bacteria, viruses, fungi, or protozoa) that take advantage of an opportunity not normally available, such as a host with a weakened immune system, an altered microbiota ), or breached integumentary barriers.
osteosarcoma a malignant tumor of bone in which there is a proliferation of osteoblasts.
parasite an organism that lives in or on another organism (its host) and benefits by deriving nutrients at the host's expense.
