Test 4-Oncology, Immunologic Diseases, Osteoporosis, Women’s Health Flashcards
Malignant tumors ______ through the _____ and ______ system and invade surrounding tissue.
Metastasize
Lymphatic and circulatory
_____ neoplasm: arises from cells that are normally of that structure
Primary neoplasm
____ neoplasm: arises from cells that metastasizes from another part of the body.
Secondary neoplasm
______ tumors do not respond to the rules that govern growth.
Malignant
A ____ tumor is one that grows slowly and the cells resemble normal cells of that tissue from which it originated. It is usually encapsulated and does NOT infiltrate surrounding tissue.
Benign
(Benign tumor)
Def: soft, fatty tumor that develops in adipose tissue, commonly found on the neck, back, and buttocks.
Lipoma
(Benign tumor)
Def: tumor of the muscle, they are rare in voluntary muscles; if found in uterus, they are called fibroid tumors.
Myoma
(Benign tumor)
Def: tumor composed of blood vessels, typically red birthmark or port wine stain
Angioma
(Benign tumor)
Def: Refers to the common mole
Nevus
(Benign tumor)
Def: an epithelial tumor that grows as a projection on the skin, polyp.
Papilloma
(Benign tumor)
Def: tumor of glandular tissue
Adenoma
Cancer cells differ from normal cells in that:
- They are [less or more?] likely to survive bc they lack the machinery necessary to sustain life.
- They have ____ nutrient demands since they are unable to make their own food
- Lack cellular _______, they do adhere to each other, but not at the same extent. It is easier for them to break free and travel.
Less likely to survive
Higher nutrient demands
Lack cellular cohesiveness
When it comes to classifying tumors, the terms used are ____ and ____.
Staging and grading
In grading of tumor cells:
Grade __ : Tumor cells are well differentiated, closely resembling normal parent tissue. Individuals have a high survival rate.
Grade I
Grade __ and __: Tumor cells are intermediate in appearance, moderately or poorly differentiated.
II and III
Grade __: Tumor cells are so anaplastic that recognition of the tumor’s tissue origin is difficult. These individuals have a poor survival rate.
IV
Which is thought to be more useful, staging or grading?
Staging
Staging neoplasms involves estimating the extent to which a tumor has spread.
Staging is often done by the ____ system.
TNM
The T in the TNM system refers to the ____ and extent of the primary tumor.
Size
The N refers to the ____ of area lymph nodes involved.
Number
The M refers to any ____ of the primary tumor.
Metastasis
Normal tissue contains cells of uniform size, shape, maturity, and nuclear structure. Normal cells also have the characteristic of cell _______.
Differentiation
Def: Refers to the specialized structure and function of any given cell and to the extent to which each cell resembles its normal parent cell.
Differentiation
In _____ cells, differentiation is altered and may be lost completely so that the cell may not be recognizable in relationship to its _____ cell. In general, the less differentiated a tumor is, the worse the prognosis.
Malignant
Parent cell
