Comp Pt

a loss of hair

an irreversible alteration in adult cells toward more primitive (embryonic) cell types; characteristics of tumor cells

not malignant

use of biological agents to treat cancer

an agent that may cause cnacer; may be chemical, physical (ionizing radiation), or biologic; biologic ____________ may be external (for example, viruses) or internal (genetic defects).

a malignant tumor of epithelial origin

treatment of illness by chemical means, that is, by medication or drugs

distortion of the sense of taste

an abnormality of development; in pathology, alteration in size, shape, and organization of adult cells

an analysis of the blood and blood-forming tissues

formation and development of blood cells

the pt is placed in a sealed chamber and given pure oxygen through a face mask. At the same time, compressed air is introduced into the chamber to raise the atmospheric pressure to several times normal. this equalizes the pressure inside and outside of the body, thereby flooding the tissues with oxygen. An increase in oxygen to the irradiated tissues can temporarily compensate for the reduction in circulation.

the production of diagnostic images, including radiography, ultrasonography, or scintigraphy.

the diffusion or accumulation in a tissue of cells or substances not normal to it or in amounts in excess of normal; in leukemia, for example, white blood cells ____________ body tissues

in its normal place; confined to the site of origin

pertaining to, or situated in the interstices (small spaces) of a tissue

within a sheath; through the theca of the spinal cord into the subarachnoid space; in leukemia, for example, the location for the delivery of various chemotherapeutic drugs

having the same genetic constitution; syngeneic

an acute or chronic progressive malignant neoplasm of the blood-forming organs, marked by diffuse proliferation of immature white blood cells (leukocytes); subsequent reduction in erythrocytes and platelets results

excision of one or more lymph nodes

tending to become progressively worse and to result in death; having the properties of anaplasia, invasiveness, and metastasis; said of tumors

transfer of disease from one organ or part to another not directly connected with it; for example, regional or distant spread of cancer cells from the site primarily involved

the point at which a pt's blood counts reach their lowest level after chemotherapy administration; do not perform any dental care during this time

any new and abnormal growth, specifically one in which cell multiplication is controlled and progressive; may be benign or malignant

the sum of knowledge regarding tumors: the study of tumors

the inflammation and ulceration of the oral mucous membranes; can increase the risk for pain, oral and systemic infection, and nutritional compromise

blood vessel compromise and necrosis of bone exposed to high-dose radiation therapy, resulting in decreased ability to heal if traumatized and in extreme susceptibility to infection

affording relief, but does not cure

abnormal depression of all cellular elements of the blood

occurrence in more than one form; the assumption of various distinct morphologic types by a single organism or cell

the treatment of disease by ionizing radiation; may be external megavoltage or internal by use of interstitial implantation of an isotope (radium)

a highly radioactive chemical element found in uranium minerals; used in the treatment of malignant tumors in the form of needles or pellets for interstitial implantation

the return of a disease weeks or months after its apparant cessation

diminution or abatement of the symptoms of a disease; the period during which such diminution occurs

a tumor, often highly malignant, composed of cells derived from connective tissue such as bone and cartilage, muscle, blood vessel, or lymphoid tissue

the succinct, standardized description of a tumor with regard to origin and spread. This clinical classification is based on physical assessments, biopsy, imaging, and endoscopy. Each sate (I-IV) consists of three components T (size of tumor); N (lymph node involvement); and M (presence or absence of distant metastasis)

limitations of opening because of spasm and/or fibrosis of the muscles of mastication and/or temporomandibular joint located in the field of radiation

dryness of the mouth because of thickened, reduced, or absent salivary flow; increases the risk for infection and compromised chewing, speaking, and swallowing. Persistant dry mouth increases the risk for dental caries
