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
Def: Indicates a disorganization of cells in which the adult cell varies from its normal size, shape, or organization. It may reverse itself or progress to cancer.
Dysplasia
Def: This is sometimes referred to as early dysplasia. It is when one adult cell changes from one type to another.
Metaplasia
Def: Loss of cellular differentiation. It is the most advanced form of metaplasia and is characteristic of malignant cell only.
Anaplasia
Def: Increase in the number of cells, resulting in increased tissue mass. This can be a normal process, however.
Hyperplasia
Def: Increase of cell mass due to tumor formation and is an ABNORMAL process.
Neoplastic hyperplasia
Factors that may increase susceptibility to cancer:
Heredity Occupation Tobacco use Diet Sun exposure
