AHII Cancer Flashcards
(96 cards)
a tumor that arises from glandular epithelial tissue
adenocarcinoma
usually refers to growths that are encapsulated, remain localized, and are slow growing
Benign
a neoplastic disorder that can involve all body organs. cells lose their normal growth-controlling mechanism, and the growth of cells is uncontrolled
cancer
a physical, chemical, or biological stressor that causes neoplastic changes in normal cells
carcinogen
a premalignant tumor that originates from epithelial cells, the skin, gastrointestinal tract, lungs, uterus, breast, or other organ
carcinoma in situ
neoplasm involving abnormal overproduction of leukocytes, usually at an immature stage, in the bone marrow (WBCs)
leukemia
neoplasm that originates from the lymphoid tissue
lymphoma
term for growths that are not encapsulated but grow and metastasize. These growths are cancerous lesions having the characteristics of disorderly, uncontrolled, and chaotically proliferating cells.
malignant
the transfer of disease from one organ or part to another not directly connected with it. Secondary malignant lesions, originating from the primary tumor, are located in anatomically distant places
metastasis
a malignant proliferation of plasma cells within the bone.
myeloma
the period of time during which an antineoplastic medication has its most profound effects on the bone marrow (greatest bone marrow suppression and platelet count is prob extremely low too); avoid anticoags and ASA during this time!
nadir
an abnormal growth, which may be benign or malignant
neoplasm
neoplasm that originates from muscle, bone, fat, the lymph system, or connective tissue
sarcoma
a method of classifying malignancies on the basis of the presence and extent of the tumor within the body
staging
specific bodily substances that seem to indicate tumor progression or regression
tumor marker
cells that have lost the capacity for specialized functions
undifferentiated cells
TNM Staging
T=size and # of tumors
N=extent of spread to lymph nodes
M=metastasis
cancer grading
GX: grade cannot be assessed
G1: well-differentiated (resembles tissue of origin) mild dysplasia
G2: Moderately differentiated moderate dysplasia
G3: poorly differentiated (little resemblance to tissue of origin) severe dysplasia
G4: undifferentiated (unable to tell tissue of origin) anaplasia
any sore that does not heal change in bowel or bladder habits indigestion nagging cough or hoarseness obvious change in wort or mole thickening or lump in breast or elsewhere unusual bleeding or discharge
warning signs of cancer
What is the definative means of diagnosing cancer and provides histological proof of malignancy
Biopsy (needle, incisional, excisional, stage=multiple needle or incisional biopsies in tissues where metastasis is suspected or likely)
What are the pros and cons of frozen vs parrafin tissue examination following a biospy?
frozen is faster (within minutes) but parrafin is clearer although it takes 24 hours
brachytherapy
the radiation source is within the client; for a period of time, the client emits radiation and can pose a hazard to others
external beam radiation (teletherapy)
radiation source is outside the client, and thus the client does not pose a risk to anyone else
Brachytherapy: unsealed radiation source
patient and excreta are radioactive for about 48 hours
