It is a procedure for determining the extent of tumor spread. Correct Answer: d. It is a procedure for determining the extent of tumor spread. Response Feedback: Staging describes the location and pattern of spread of a tumor. Staging does not involve biochemical testing of tumor cells, or the histologic examination of tissues, which is done with cancer grading. CT, MRI, and PET imaging techniques have allowed for noninvasive cancer detection. Question 2 0.125 out of 0.125 points Proto-oncogenes Selected Answer: b. are normal cellular genes that promote growth. Correct Answer: b. are normal cellular genes that promote growth. Response Feedback: Proto-oncogenes are normal cellular genes that promote growth. Proto-oncogenes are not the same as oncogenes, which are mutant proto-oncogenes. They are different from tumor- suppressor genes and do not alter tumor-suppressor genes. Mutational events lead to oncogenes, a mutated proto-oncogene.

Response Feedback: Necrosis refers to death of cells/tissue and is not reversible. Metaplasia refers to the replacement of one differentiated cell type with another from persistent injury and is reversible when the injury stops. Atrophy occurs because of lack of use of an organ and is reversible. Hyperplasia is an increase in the number of cells from increased physiologic demands or hormonal stimulation and is reversible.

Correct Answer: d. secondary prevention.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
