Principles of Disease
Question | Answer |
---|---|
new growth | neoplasm |
a swelling or a neoplasm | tumor |
Not all neoplasms form tumors. | True |
a malignant disease of the bone marrow that causes an increase in white blood cell production and might not form distinctive tumor | leukemia |
a large tumor or swelling filled with blood; commonly called a bruise or contusion | hematoma |
1) Appearance and growth pattern 2) Tissue of origin, or type of body tissue from which they grow | 2 ways to classify neoplasms |
neoplasms that are confined to a local area and do not spread | benign |
exhibit characteristics of invasion and metastasis | malignant |
the spreading of the neoplasm into local or surrounding tissue | invasion |
the spread of the neoplasm to distant sites | metastasis |
the most common type of malignant neoplasm arising from epithelial tissue | carcinoma |
a malignant neoplasm arising from connective tissue | sarcoma |
Neoplasms are classified or named according to the tissue from which they grow along with the suffix "oma" for tumor. | True |
A benign tumor of epithelial tissue such as a gland would be adenoma | True |
If it is a malignant neoplasm, the name becomes adenocarcinoma. | True |
malignant neoplasms of lymphatic and blood-forming organs and lymphatic tissues | lymphomas |
glandular epithelium | benign - adenoma malignant - adenocarcinoma |
squamous epithelium | benign - epithelioma malignant - squamous cell carcinoma |
adipose | benign - lipoma malignant - liposarcoma |
cartilage | benign - chondroma malignant - chondrosarcoma |
bone | benign - osteoma malignant - osteosarcoma |
glial | only malignant - glioma |
blood | only malignant - leukemia |
the process of individual specialization | differentiation |
vessel growth or new growth of blood vessels | angiogenesis |
an individual begins to lose weight and appear thin, frail, and weak | cachexia |
overgrowth of cells that cause an increase in the size of the tissue | hyperplasia |
Hyperplasia usually occurs in response to a stimulus, and the growth stops when the stimulus stops | True |
Neoplasms are not only an increase in cell number, but new or different in their appearance from their cell of origin, or mother | True |
cancer-causing agent or substance | carcinogen |
the process of using light, short waves such as ultraviolet or x-ray | radiation |
abnormal hyperplasia | dysplasia |
atypical cells are "just sitting" in the epithelial layer of the tissue and have not broken through the basement membrane and invaded the surrounding tissue | carcinoma in situ |
Sarcomas do not use the lymphatic system as readily as carcinomas. | True |
determines the degree of differentiation of the neoplasm | grading |
considers the degree of spread | staging |
undifferentiated | neoplastic |
The higher the degree of differentiation, the better the prognosis. | True |
removing a small piece of tissue for microscopic examination | biopsy |
Grading and staging are two predictors of prognosis; staging is the better indicator. | True |
cancer development | cardinogenesis |
a cellular adaptation in which the cell changes to another type of cell | metaplasia |
a test to screen for cervical cancer | pap test |
Change in bowel or bladder habits A sore that does not heal Unusual bleeding or discharge Thickening or lump in breast Indigestion or difficulty swallowing Obvious change in a wart or mole Nagging cough or hoarseness | CAUTION |
examination of cells | cytology |
a technique that enables the pathologist to make a rapid determination of the tumor condition: benign or malignant | frozen section |
using pharmacologic therapy in the treatment of cancer | chemotherapy |
treatment aimed and curing | curative |
treatment to relieve symptoms | palliative |
