Metaplasia is
the replacement of one differentiated cell type with another.
Necrotic death of brain tissue usually produces _____ necrosis.
liquefactive
The primary effect of aging on all body systems is
decreased functional reserve.
Retroviruses are associated with human cancers, including
Burkitt lymphoma.
The cellular change that is considered preneoplastic is
dysplasia.
In general, a cancer cell that is more tissue-specific differentiated is more likely to be aggressive.
False
Paraneoplastic syndromes in cancer involve excessive production of substances by multiple means. A common substance found in excessive amounts resulting from cancer paraneoplastic syndromes is
calcium.
Cancer grading is based on
cell differentiation.
The cellular response indicative of injury because of faulty metabolism is
intracellular accumulations.
Malignant neoplasms of epithelial origin are known as
carcinomas.
The most common tumor-suppressor gene defect identified in cancer cells is
P53.
Familial retinoblastoma involves the transmission of what from parent to offspring?
Mutant tumor-suppressor gene
The hypermetabolic state leading to cachexia in terminal cancer is thought to be because of
tumor necrosis factor.
Carbon monoxide injures cells by
reducing oxygen level on hemoglobin.
Your patient is scheduled for a staging procedure. She wants to know what that means. The correct response is which of the following?
It is a procedure for determining the extent of tumor spread.
After bronchoscopy and histologic examination of a suspected tumor, your patient is diagnosed with primary bronchial carcinoma. Thus, the tumor
is malignant.
After surgery to remove a lung tumor, your patient is scheduled for chemotherapy, which will
kill rapidly dividing cells.
Of the statements below, the accurate statement regarding nutrition and cellular health is
deficient cellular uptake by one cell type may contribute to excess nutrient delivery to other cell types.
Proto-oncogenes
are normal cellular genes that promote growth.
