Introduction
This comprehensive test bank assesses mastery of the molecular and cellular
mechanisms that drive cancer initiation, progression, and treatment response
as presented in the third edition of The Biology of Cancer by Robert A.
Weinberg. It evaluates understanding of oncogenes, tumor suppressor genes,
signaling pathways, cell cycle regulation, apoptosis, angiogenesis, metastasis,
tumor immunology, and targeted cancer therapies. Questions are structured in
multiple-choice and scenario-based formats to emphasize clinical application,
experimental interpretation, and real-world decision-making. A strong
emphasis is placed on the integration of foundational molecular biology with
translational and clinical oncology concepts.
CHAPTER 1: THE BIOLOGY AND GENETICS OF CELLS AND
ORGANISMS
1. Which of the following best defines a neoplasm?
A. A reversible increase in cell number due to injury
B. An abnormal mass of tissue with uncoordinated growth that persists after
the cessation of stimuli
C. A fluid-filled cyst lined by normal epithelium
D. A collection of inflammatory cells responding to infection
B
RATIONALE: A neoplasm (tumor) is an abnormal mass of tissue
resulting from excessive, uncontrolled cell proliferation that is not
coordinated with normal tissue and persists after removal of the initial
stimulus. This definition distinguishes neoplasia from reversible hyperplastic
or inflammatory responses.
2. The term "anaplasia" refers to:
,A. Increased specialization of tumor cells
B. Loss of structural and functional differentiation of cells
C. Formation of a fibrous capsule around a tumor
D. Programmed cell death
B
RATIONALE: Anaplasia is the lack of differentiated features in cancer
cells, often associated with aggressive behavior. It is a hallmark of malignancy
and reflects the dedifferentiated state of cancer cells.
3. A benign tumor differs from a malignant tumor primarily because
benign tumors:
A. Grow more rapidly
B. Do not invade surrounding tissues or metastasize
C. Are always encapsulated
D. Consist of poorly differentiated cells
B
RATIONALE: Benign tumors remain localized, do not invade adjacent
structures or metastasize, whereas malignant tumors have the capacity to
invade and spread. Benign tumors are generally well-circumscribed and retain
a greater degree of differentiation.
4. Which of the following is a characteristic of carcinoma in situ?
A. Invasion of the basement membrane
B. Metastatic spread to lymph nodes
C. Neoplastic cells confined to the epithelium without basement membrane
invasion
D. Extensive desmoplasia
C
RATIONALE: Carcinoma in situ is a pre-invasive lesion where abnormal
cells occupy the full thickness of the epithelium but have not breached the
, basement membrane. It has not yet acquired the capacity for invasion or
metastasis.
5. The term "metastasis" refers to:
A. Tumor growth at the primary site
B. Direct extension of tumor into adjacent tissue
C. Spread of cancer cells to distant organs
D. Formation of a secondary benign tumor
C
RATIONALE: Metastasis is the spread of cancer cells from the primary
tumor to distant organs via lymphatic or hematogenous routes, where they
establish secondary tumors. It is the most lethal attribute of cancer.
CHAPTER 2: THE NATURE OF CANCER
6. In a hypothetical cross between two fruit flies, one with red eyes and
one with white eyes, all resulting progeny had red eyes. This would
suggest that:
A. The red-eyed trait is recessive to white eyes
B. The red-eyed trait is dominant to white eyes
C. The red-eyed and white-eyed genes are co-dominant
D. The eye color trait is most likely coded for by multiple genes
B
RATIONALE: When all offspring express one parental phenotype, that
trait is dominant. The red-eyed trait is dominant to white eyes, as
demonstrated by the uniform red-eyed progeny. This is a classic Mendelian
inheritance pattern.
7. Which of the following mutations would be MOST likely to be
retained in a species gene pool?
